Science fiction hasn’t prepared us to imagine machine learning

I've published two novels that go there: 2011's "Rule 34", and -- coming out this September -- "Invisible Sun", and in both books ML is very much a subaltern aspect of the narrative. That is, neither book would have a plot without the presence of ML, but it's not really possible in my opinion to write a novel about ML in the same way that the earlier brain-in-a-box model of AI could form the key conceit of books like "2001: A Space Odyssey", "The Adolescence of P-1", or "Colossus" (examples from the 1960s and 1970s when it was still a fresh, new trope rather than being pounded into the dirt).
So it probably shouldn't surprise anyone much that SF hasn't said much about the field so far, any more than it had much to say about personal computers before 1980 or about the internet before 1990 -- what examples there are were notable exceptions, recognized after the event.
For example, it brings to mind some combination of Minority Report and Eagle Eye, say. Where a surveillance state combined with ML analysis leads to something akin to pre-crime arrests and the fight back against that.
While I haven't seen Minority Report or Eagle Eye, this aptly describes the anime TV series Psycho-Pass (2012). If I remember correctly, the show is mostly focused on the effects of having a crime-coefficient system.
I got a counterexample:
Person of Interest [0] was a crime series from 2011-2016 premised around machine learning. The opening narration from each episode of the first season[1]: You are being watched. The government has a secret system, a machine that spies on you every hour of every day. I know because, I built it. I designed the machine to detect acts of terror but it sees everything. Violent crimes involving ordinary people. People like you. Crimes the government considered "irrelevant". They wouldn't act, so I decided I would. But I needed a partner, someone with the skills to intervene. Hunted by the authorities, we work in secret. You will never find us. But victim or perpetrator, if your number's up, we'll find you.
Revealed in flashbacks over the first season, the government doesn't have access to the system. It runs independently (even from its creator) and just provides information.
Being TV it does of course expand past the original premise, with a reveal that it's not just a machine learning system but the world's first true AI, and later another AI with conflicting goals is brought online. But for the first season at least, the machine sticks to the role described in the narration, and appears to be just a machine learning system.

Did you mean to say "... which it is not", or "which it is, thus the boringness"?
But man, I can't argue the incredible results it creates. Perhaps that's why people do it, for the ends not the means.
What's described there is the predicting patterns, which is a part of intelligence but there's much more to discover and invent. Even within the 'optimization' task there's huge differences in the leaps from NNs to DNNs and from DNNs to AlphaGo/Zero. The details are what make it interesting.
If we were to understand exactly how the brain operates and learns, we'd see that it's solved/solving just an optimization problem, but that doesn't make it uninteresting.
I mean, the fire, the water, the ice, the amazeness of life and intelligence are still there. You just gained a new foundational view. Now you can understand and manipulate better what you already knew, maybe now you learned about plasma, or even extremely advanced and mysterious phenomena like bose-einstein condensates or superfluidity. The old wonders are still there, you've gained new ones.
I'm not going to claim complete cognitive equivalence (or even preference) between the two states of mind, but it is a bit like childhood: firmly believing in Santa Claus, or Wizards or whatever can be exciting, perhaps more exciting than knowing they are myths; but growing up and understanding they are mythical brings new opportunities, capabilities, and even new mysteries you could not reach before (buying and building whatever you want, vast amounts of knowledge, understanding more about technology and society, etc.). It's the adults that keep us alive and well, that make decisions for us and for society at large. So perhaps (although I'm not entirely convinced by the cumulative argument) truth is a sacrifice, but it is one well worth bearing, at least for me. I am deeply interested in how intelligence works, in how "the sausage is made" (at least for certain highly useful sausages that compose the fundamentals of the world).
Even more, understanding is above all a responsibility, if not for all of us, at least for some of us, or hopefully in one way or another for most of us.
I can't recommend enough Feynman on Beauty: (this argument is largely inspired by that)
https://fs.blog/2011/10/richard-feynman-on-beauty/
In the same vein, intelligence to me used to be a black box where you got input from the world, some kind of wondrous magic happened, and then you got talking kids, scientists, artists, and so on. Now I still view it as wondrous, but now I understand the fundamental is apparently a network-like structure with functional relationships that change, adapt to previously seen information in other to explain it, that there are a number of interesting phenomena and internal structures (going well beyond the simple idea of 'parameter tuning') that can be formalized -- essentially the architecture of the brain (or better, 'a brain').
To give an example, there have been formalizations of Curiosity, i.e. Artificial Curiosity, and I consider it essential for an agent interacting independently in the world or in a learning environment (part of the larger problem of motivation). How amazing is it to formalize and understand something so profound and fundamental to our being as Curiosity? I felt the same way about Information theory years ago. How amazing is it that we've built robots (in virtual environments), and it works -- they're curious and learn the environment without external stimulus?
Above considerations aside, I find that amazing, beautiful, awesome.
The basic idea is, forget about what you think is beautiful or motivational. Suppose you could choose to be motivated by something. Would you choose to be motivated by superficial mystery, or by deep knowledge of how things are? Should you choose to find beautiful just the surface of the flower, or also the wonders of how it works, its structure as a system, the connections to evolution and theory of color and so on -- all of which could turn out to be useful one way or another. If you could choose, would you choose to be exclusively motivated by the immediate external appearance or by the depth and myriad of relationships as well?
Unfortunately, (unlike AI systems we could design) I don't think we have complete control of our motivation -- our evolutionary biases are strong. But I'm also fairly certain much of our aesthetic sense can be shaped by culture and rational ideals. If I hadn't heard Feynman, watched so many wonderful documentaries (and e.g. Mythbusters) and many popularizers of science, perhaps I wouldn't see this beauty so much as I do -- and I'm grateful for it, because I want to see this beauty, I want to be motivated to learn about the world, and to improve it in a way.
Yes it is exactly what I'm saying. I'm less interested because of this. I could turn it around and also say that with your extremely positive attitude you can look at a piece of dog shit and make it look "amazing." Think about it. That dog shit is made out of a scaffold of living bacteria like a mini-civilization or ecosystem! Each unit of bacteria in this ecosystem is in itself a complex machine constructed out of molecules! Isn't the universe such an interesting place!!!!!
This history of that piece of shit stretches back though millions of years of evolutionary history. That history is etched into our DNA, your DNA and every living thing on earth!!! All of humanity shares common ancestors with the bacteria in that piece of shit and everything is interconnected through the tree of life!!! We can go deeper because every atom in that DNA molecule in itself has a history where the scale is off the charts. Each atom was once part of a star and was once part of the big bang! We, You and I are made out of Star Material! When I think about all of this I'm just in awe!!!! wowowow. Not.
I'm honestly just not interested in a piece of shit. It's boring and I can't explain why, but hopefully the example above will help you understand where I'm coming from.
You see, there are people out there that legitimately, professionally study poop for a living. I read a book (well, part of it) Gorillas in the Mist, by Dian Fossey, and there is an appendix on parasites, mostly using fecal analysis. Literally, a chapter on poop and worms. Reading it without prejudice, I found it extremely interesting.
Should we just say 'ewww', 'dog shit is boring, no one should study it'; or should we give it the benefit of doubt? What makes something interesting? I'm sure you could study poop and parasites for years -- they tell you about the diet of an animal without having to follow it day and night, they reveal parasites that may be of health concern for human poop.
Should we, as a society, forsake all study of poop by deeming it boring? Are those people that study poop, and don't find it boring, wrong? Or maybe they secretly go about their job finding it extremely boring? I doubt it.
> Yes it is exactly what I'm saying. I'm less interested because of this.
I think you're falling victim to reductionism. I meant my example literally: because everything is just atoms, should everything be boring? (if intelligence is just parameter adjustment) I suppose you don't find literally everything boring despite literally everything being just interacting atoms.
You could have this reductionist attitude on anything really:
Once I found out mathematics is just manipulating symbols, I am less motivated/Once I found math is just deriving from axioms, I am less motivated/Once I found life is just a bunch of organisms fighting for survival, I am less motivated
Does it really make sense to be less motivated, is the subject matter really boring, or are you just taking a reductionist argument and replacing the nuance and complexity and beauty of the real thing with a reductionist model (that doesn't really tell us much about how it works)?
Going even further: forget about machine learning. You can formulate physics so that Nature, everything, is locally minimizing (optimizing) a high-dimensional energy function. Literally everything in the Universe is parameter tuning! Oh no, everything is boring! :p
To me, then, there are three pillars of what makes something interesting:
1) It is useful;
2) It has breadth of knowledge (i.e. it's not a trivial matter you can learn in one sitting);
3) It has structure (i.e. it's not just rote memorization)
If I pointed someone to a perfectly uniform white wall and with an extremely positive attitude he declared "Amazing!", and spent hours going "Look how white the white is... what purity, I will stand here all day contemplating different aspects of the whiteness", I'd think he's yes a bit different. But it's not difficult to argue why we think that.
Another point of confusion, is that we're not all in the same situation. Each person has a set of skills, and a background knowledge, such that, for an individual, a subject can seem more or less useful, more or less related to everything he knows (thus much structured, connected, rich), and more or less aligned with his skills. It's perfectly acceptable to declare something as not interesting to him, but not plain boring, universally uninteresting.
I cannot advance much further without talking about the specifics of intelligence: do you know learning theory (PAC learning, etc.), reinforcement learning, all the interesting mathematical structures e.g. in convnets, GANs, Wasserstein-GANs, cognitive psychology, neurobiology, etc.. I think my argument is easy because in this case 'intelligence' is so vastly broad, reaching most areas of math, engineering and science that I doubt with serious effort someone could still blankly classify it as uninteresting (unless you literally do find everything uninteresting... you should be a bit worried about that, I'm serious).
And like in every field in practice one would not sit every day thinking in abstract terms about 'intelligence' -- you would be trying to solve specific problems e.g. what kind of neural architecture could be used to solve a specific problem, what kind of data augmentation can I contribute, or more advanced problems like what is the internal architecture of a robot.
Thank you for the opportunity of laying out those thoughts :)
(Please read my other comment as well, and I have a few things to add w.r.t. hyper-specialization)
Every time your brain sees something related to "science" it automatically dumps a gallon of dopamine into the happy center of your brain giving you euphoria equivalent to a line of heroin.
I wonder what's your positive spin on the holocaust? There's actual science that came out of that event.
I enjoy the creative challenge of applying domain knowledge when building (for example) linear or bayesian regressions. In contrast, DL seems like a whole bunch of hyperparameter tuning and curve plotting. Curious to see if this assessment seems correct from those more experienced...
One question, if you're up for doing any questions: what do you think about the use of drones and loitering munitions in the recent Azerbaijani-Armenian War of 2020?
Thanks again for all the hard work!

Imagine star trek where instead of Data being one android, you just had a ton of machines that could do everything better than humans. No point for the humans to explore space or do anything. The end.
Imagine in Minority Report where Tom Cruise is instantly caught because his whereabouts can easily be tracked and triangulated, by his gait, infrared heart signature, smell, and a number of other things. Movie takes 2 minutes. The end.
In fact, this is the world we are building for ourselves. We're going to be like animals in a zoo, unable to affect nothing. Just like a cat has no idea why you're doing 99% of the things you do, but has to go along with it, similarly you will have no idea why the robot networks do 99% of their activities, you just kinda live your life with as much understanding as a cat has in your house, as you go about your daily business.
The closest I can think of is Isaac Asimov's "I Robot" maybe. And even there, the robots weren't in charge really.
Agh, I can't find it now, but there's a short film half based on this: A time traveler from the future is identified instantly because she's in two places at once. The short has both of them in adjacent interrogation rooms, with two onlookers - a rookie and an experienced investigator - talking about how to identify time travelers. It ends with the experienced one commenting that they've been showing up more and more often.
Minority Report might not be possible with such technology, but it does open different possibilities.
DUST make a lot of cool sci-fi short films, worth checking some of their others too https://www.youtube.com/c/watchdust/videos e.g. Bleem, the number between 3 and 4, slightly remeniscent of the film Pi and the crazy mathematician trope https://www.youtube.com/watch?v=qXnFr1d7B9w or Orbit Ever After, a love story in a dystopian Brazil style future of orbital habitats https://www.youtube.com/watch?v=DpFXMIxlgPo
And just because, from another channel a https://www.youtube.com/watch?v=vBkBS4O3yvY a short about quantum suicide - One-Minute Time Machine | Sploid Short Film Festival.
Maybe, or maybe it's just an old trope as you point out. So much of science fiction assumes some level of intelligent computers and has since the beginning. The phrase "machine learning" is really a rebrand of the "thinking machines" of the 60s and artifical intelligence" of the 70s and 80s. Even in the old Star Trek TV series, you had people talking to the computer, not unlike we talk to Alexa, Siri and Hey Google today.
That said, now that people are seeing ML affect their lives directly, there is a lot of exploration that may be possible, as perhaps, ML is just not science fiction anymore.
Alexa and Siri and Google Home aren't going to take over the world or try to become human, and aren't infallible or even particularly smart. They're a speech input interfaces over a search engine with some jokes hardcoded in. From a technical standpoint, very impressive; from a fiction standpoint a dead end
It dug into deep fakes and how they could be used to create a massive propaganda machine. I wouldn't call that boring.

To me it's akin to several scenes in the film "War Games" where you basically have to make a rogue AI in a computer sexy on film.
"Show a computer thinking. Make it scary. Inhuman. Enhance that it's impersonal."
So we get a camera person slowly walking around an obelisk-like table with ominous music. "This is where the AI lives, thinking on how to rain nuclear fire upon the vile Soviets, no humans need interfere, enhance and intensify, will Tic-Tac-Toe save us from our folly". And around and around the evil obelisk table we go watching bits flip up and down back and forth with nuclear missiles in question.
You can find similar elsewhere. Dramatic flashing lights on a server rack, a human taken over by external forces blindly jabbing at a keyboard or keypad with intense purpose. All of a sudden from these wonders computational magic happens.
I especially appreciate this discussion. It’s fun to think about the gaps in our imagination. Especially when it comes to science fiction, those gaps are often wider than we think.
Good luck with your work! I’ll be on the lookout for Invisible Sun, unless you recommend a different title.
Besides ML, do you have any other fururist predictions that are not being realized in science fiction?
reality can be boring. Reality dictates that we travel at a fraction of the speed of light. We cannot fix things we did. We have a limited lifespan.
Honestly the made-up stuff makes fiction a lot more entertaining. Time travel is really fun (though primer required a dive into wikipedia to unravel). Warp drives and wormholes open the universe to exploration. Living forever might be just as fun as time travel - you can fix stuff forward or just see it all. I don't mind suspending my disbelief.
EDIT: On the other hand, there might be one real subject that is interesting from
https://jsomers.net/i-should-have-loved-biology/
it had a quote:
Imagine a flashy spaceship lands in your backyard. The door opens and you are invited to investigate everything to see what you can learn. The technology is clearly millions of years beyond what we can make.
This is biology.
- Bert Hubert, "Our Amazing Immune System"
Realistic SF is more entertaining IMO. e.g. I much prefer The Expanse or The Martian to Star Trek or Star Wars.
- When building an ML model, you think much less about the structure of the model and much more about getting a variety of data to feed it. One could imagine some really silly situations. If you're training an affect-recognition model, you might want to contract every single actor in hollywood to act out a single scene. Maybe your voice recognition model is not working on certain people, so you hunt down a specific person and force them to read all of Shakespeare's work out loud. You might work on self-driving problems, and every day you instruct a full village of people to enact a precise ballet of driving, walking, and roadwork, to get the autonomous brain to learn some weird corner case of reasoning. Similar to Player Piano, so many people will be working on non-directly-productive work, almost play-acting work so a computer can do it for real.
- Sometimes ML doesn't work in really weird specific situations. In the 90s, your program could stop working because the lighting and shadows changed, but now the reasons for something failing are so much more obscure. What is it like becoming an expert in psychology for something that doesn't even really think? What does that person do day-to-day and what does their boss think of them? Is it more like being an independent psychiatrist, or more like a police detective? (then again, I'm drifting into an Asimov plot even as I write this...)
- Each object you train an ML model on takes a certain amount of investment, in data collection, in debugging, and in adjusting the training process. Each object adds expense, so maybe a solution is to stop adding objects? Maybe your Alexa enhanced home edition was built in 2025, so to keep your house in order you can't buy items made from 2026 onwards. Or maybe it's a big societal issue, so the government mandates that every new item created must pay some kind of registration fee. Maybe it only allows 10 new items per year. Some people would be pretty unhappy about that.
Maybe you're right! Maybe switching from straight edges screws to philips screws makes for a really boring story, because we've already written every story that accounts for some kind of screw driver.
I assume that you are aware but ML really is moving towards more general purpose AI.
For example, the Turing Award winners for Deep Learning (Hinton/LeCun/Bengio) have all listed the numerous shortcomings of today's narrow AI and public declared an earnest interest in more human-like capabilities. And started serious research programs attacking those shortcomings. With many of the current generation of researchers quite engaged with them.
There is progress on self-supervised learning, transfer learning, multimodal learning, more powerful models such as the transformer, extracting more accurate and fundamental latent spaces, model-based, online learning, more modular systems, 3d reconstruction from images and even videos, J. Tenenbaum's clear functional explanation beginning to be addressed with the new neural network tools, etc. Most of the results are not at the present moment inspiring enough to base a novel around. But there are many promising threads.
As someone on the forefront of ML, you would expect me to be in a position to reap the benefits. It's possible I am incompetent. But I often wonder what we're doing, chasing gradients and batchnorms while training classifiers to generate photos of lemurs wearing suits.
I try not to dwell on it too much, since I truly love the work for its own sake. But one must wonder what the endgame is. The models of consequence are locked up by companies and held behind an API. The rest are nothing more than interesting diversions.
I've been reading some history of math and science, and it seems like many of the big discoveries were made from people pursuing the work for its own sake. Feynman loved physics long before physics became world-changing. But if physics never lead to the creation of the bomb, would it have been so prestigious?
We seem to be lauding ML with the same accolades as physics during the postwar period. And I can't help but wonder when it will wear off.
ML will be a fine tool for massive corporations, though, for endless reasons. But I was hoping for a more personal impact with the work. Something like, being able to enable a blind person to use a computer in a new way, or... something more than memes and amusement.
Perhaps doing the work for its own sake is enough.
Of course, just like any other technology. What else could be the case? I don't see this as a point of concern. Is it overhyped - yes (salespeople gonna sell); is it still useful in a number of applications - also yes.

Now, what about neural networks? Well, you replace that guy with a one liner math function and call it a day. Now consider that you have billions of guys like that in your head, way more than any of our simplified neural networks, and it becomes very clear how far we are from getting anywhere. They are really important, they decide who to connect to, where and when to send signals etc. Neural networks doesn't model neurons, just the network hoping that the neuron wasn't important.
Everything you say is true, and more. There is another kind of cell in the brain that outnumbers neurons about ten to one. They’re called glial cells and they come in numerous forms. We used to think they were just support cells but more recently started to find ways they are involved in computation. Here is one link:
https://en.m.wikipedia.org/wiki/Tripartite_synapse
The computational role they have is unclear so far (unless there is more recent stuff I am not aware of) but they are involved.
We are nowhere near the human brain. I think it will take at least a few more orders of magnitude plus much additional understanding.
GPT-3 only looks amazing to us because we are easily fooled by bullshit. It impresses us for the same reason millions now follow a cult called Qanon based on a series of vague shitposts. This stuff glitters to our brains like shiny objects for raccoons.
What this stuff does show is that generating coherent and syntactically correct but meaningless language is much easier than our intuition would suggest:
https://nbviewer.jupyter.org/gist/yoavg/d76121dfde2618422139
Those are extremely simple models and they already produce passable text. You could probably train it on a corpus of new age babble and create a cult with it. GPT-3 is just enormous compared to those models, so it’s not surprising to me that it bullshits very convincingly.
Edit: forgot to mention the emerging subject of quantum biology. It’s looking increasingly plausible that quantum computation of some kind (probably very different from what we are building) happens in living systems. It would not shock me if it played a role in intelligence. The speed with which the brain can generalize suggests something capable of searching huge n-dimensional spaces with crazy efficiency. Keep in mind that the brain only consumes around 40-80 watts of power while doing this.
They’re really just freaking enormous regression models that can in theory fit any function or set of them with enough parameters. Think of them as a kind of lossy compression but for the “meta” or function itself rather than the output.
The finding that some cognitive tasks like assembling language are easier than we would intuitively think is also an interesting finding in and of itself. It shows that our brains probably don’t have to actually work that hard to assemble text, which makes some sense because we developed our language. Why would we develop a language that had crazy high overhead to synthesize?
It absolutely could be used to manufacture spam and low quality filler at industrial scale. Those couple Swedish guys that write almost all pop music should be worried about their jobs.
(To be clear, my argument wasn't that ML isn't useful -- but rather that individual lone hackers are less likely to be using ML to achieve superman-type powers than I originally thought. Supermen do exist, but they are firmly in the ranks of DeepMind et al, and must pursue projects collectively rather than individually.)
For a single individual to have "superhuman" impact with ML, they need not only generic ML knowledge, but also specialized knowledge of some domain they want to impact. Actually, because ML has become so generic (just grab a pre-trained model, maybe fine-tune it, and push your data through it) a very shallow understanding of the fundamentals is probably enough, and in-depth domain knowledge much more important.
That doesn't mean generic ML research isn't important, it's just that it has an average impact on everything, not a huge impact in one specific area.
(I suspect many hobbyist ML projects are about generating entertaining content because everyone has experience with entertainment, even ML researchers.)
Of course policy activism is far less sexy than building new shiny things, so there's little interest in that.
Imaging based diagnosis could read presence or absence of particular gene mutations from the images so that the genes can be silenced by the drugs.
Imaging based diagnosis could also figure out whether a particular cancer precursor is going to develop into invasive cancer and do it better than the experts we have now (otherwise we wouldn't use the AI).
This can also be done cheaper than paying consultants to figure it out and it can be done in locations where they don't have the specialists.
Some companies working in the field (some already have tools approved for use on patients):
https://analogintelligence.com/artificial-intelligence-ai-st...
>Imaging based diagnosis could also figure out whether a particular cancer precursor is going to develop into invasive cancer and do it better than the experts we have now (otherwise we wouldn't use the AI).
Where is the evidence for these claims, other than a VC hype sheet? Like real clinical trials. These claims also show a fundamental misunderstanding of what this data can tell us. Imaging data doesn't give you tumor genetic profiles. It can give you tumor phenotype, which is associated with specific mutations. To get the true genetic profile you need to do deep sequencing at tens of thousands of dollars per tumor, and even then you have the problem of tumor heterogeneity, which lets the cancer evade the treatment.
A major concern I have working in this space is that we're selling people on grand promises of far off possibilities rather than what we can actually deliver right now.
https://www.nature.com/articles/s41591-019-0462-y
Of course changes in the genotype that impact the phenotype enough to influence the disease also influence the morphology of the cells.
But this is area of active research so you can't expect phase 3 clinical trials. Yet.
EDIT: here is another more "perspective" paper how such tools could be used and integrated in current processes, from the same authors

How does epigentics complicate this further, is it that it wides the number of inputs into a biochem system
As far as what we don't know, I'm not sure there's a list. Lack of knowledge implies lack of awareness. I can offer one example: We don't know much about the processes by which collagen fibers are grown and assembled into μm- and mm-scale load-bearing structures in tendon, ligament, bone between embryo and adult, particularly in mammals. Or the extent to which collagen fiber structures are capable of turnover in adults; healing might only be possible by replacement with inferior tissue such as scar.
Personally, I think the complexity of biological systems, and the difficulty of observing their components directly when and where you'd want to, means that they can only be understood with the help of machines. Not necessarily using convolutional neural networks though.
So observing that gene X impacts biochemical pathway in some way Y is already really difficult when there are tons of other genes at play. Add on the fact that these genes could be triggered to stop expressing themselves in certain conditions and it makes the whole process of figuring out what is really going on that much more difficult. Even if we can make some observation, there are tons of contextual situations which would potentially invalidate that observation.
It'd be really hard to train a computer when to stop digging because there's nothing find, or when to keep digging because this patient really doesn't feel like a psych case. And the tests and doagnostics aren't without risk and cost.
I've had a greybeard doctor in my personal life that somehow read between the lines and nailed a diagnosis despite my primary symptoms being something else entirely. (I had recurring strep tonsilitis for months and yet he just somehow knew to step back and order a mono test. It came back negative the first time, and he knew to have me tested AGAIN, and lo and behold it was positive.) None of symptoms were really consistent with mono. I tested positive for strep each time and antibiotics would clear it.). Thankfully I happen to be allergic to the first line antibiotic because if you give amoxicillin to someone with mono they'll get a horrible rash all over their body in like 90% of people.
As an MD with a special interest in statistics, color me skeptical. I'd love to be proven wrong though, so please provide references.
Edit: yeah, so the way this whole thread is developing really goes to show (yet again) that medical AI hype is relying as strongly as ever on the fantasies of people who've never seen any clinical work.
Cool! Which hospital is that? Is the clinical staff happy with the results?
Personally, I've never seen any medical ML application that made my job easier. But it would be nice to see.
I can answer that: close to zero. Clinicians don't want stuff that makes recommendations, as good as they may be. They want a bycicle for the mind: something that helps them visualize, understand the big picture and anticipate better. And also ensure that trivial stuff to do is not forgotten (now that's the place a recommender engine could fit in). That's a fundamental misunderstanding of what a clinician's job is that is unfortunately very common.
What do you ask of your software tooling? Do you want something that just tells you what to write? No, you want a flexible debugger. A compiler with precise error messages. You want a profiler with a zillion detailed charts allowing you to understand how everything fits together and why such and such is not the way you anticipated. Same thing for medicine until the day machines will actually do better than humans, which is not tomorrow nor the day after.
Otherwise it's kind of like, I have invented SkyNet in my garage but I am only using it to become richer through the stock market.
It's admirable that you are working on saving human lives. But are human lives actually saved?
From the parent:
> This work has greatly increased accuracy in diagnosis, saving lives.
We don't know if that's a good thing yet.
But I agree with the sentiment that progress is often driven by intrinsic motivation.
I guess I’m somewhat on the opposite side of the fence. I see it everywhere... although yes I think Big Bang things are probably a few years off
As far as I have seen experts see autonomous driving as at least ten years away (unless you look at the sliding "next year" BS from Tesla) so I don't think we're only a few years off big changes because of ML. More like 10-15.
My perception of machine learning as a mere dabbler myself is that "machine learning" is just a sci-fi name for what's essentially applied statistics. In places where that is useful (e.g. clustering ads by feature similarity to highlight unclassified ads that appear similar to known trafficking ads), then machine learning is useful. It's not necessarily as one-size-fits-all as, say, networking or operating systems are, but in cases where you can identify a useful application of statistics, machine learning can be a useful tool.
also you can just "throw all the data" at an svm or random forest, or any number of similar models. Automated parameter tuning can be convenient, but it's prone to overfitting and doesn't eliminate a lot of the actual work
As a physicist I used to say that ML is simply non-linear tensor calculus. (I’m not sure if I’m right though)
If this is not amazing to you there is only one possible explanation for that (by the almighty himself):

For example, I searched for "How to do Y"
The google infobox says "X"
Clicking into the article to find the more explanation, and I read "X is never the right way to do Y, you should do Z instead"
I've seen this happen enough that I literally cannot trust those snippets.
A bit of an absurd, exaggerated example, Google search (or ask your Google Home) "Is the moon made of cheese"
I'm just saying that at the final count we see our lives stay the same except when they sometimes get worse and this has and will continue to affect our sense of wonder and our capacity to be surprised.
> Feynman loved physics long before physics became world-changing.
Feynman was an intensely practical person and learnt a lot about physics from e.g. fixing his neighbours' radios as a child. And radio is certainly something I'd class as "world-changing". He loved physics because of the things you could build and create, and did not enjoy abstraction or generality for its own sake.
A better example for your argument might be Hardy, who explicitly stated that his love of number theory was partly due to its abstraction and uselessness. This was long before it had critical applications in cryptography.
- Real marketing(people misunderstand marketing as sales and advertising) that is the study of people's needs
-History, in particular History of inventors and inventions that really changed the world, like paper(also papyri and pergamine) Gutenberg press, crossing the Atlantic on a ship,electricity, bicycles and Ford cars, antibiotics, rockets, nuclear power, Internet.
-Read books on innovation, like "The Innovator's Dilemma" that talks about most innovation having organic growth, looking so small at the beginning and then growing proportionally to itself. Almost everybody that cares about absolute things, like fame or fortune, ignoring it at first because the absolute value is so low.
Once you do that you will literally "see the future". You will recognize patterns that happened in the past and are happening right now. And you will be able to invest or move to those areas with a great probability of success.
PostEra - A medicinal chemistry platform that accelerates the compound development process in pharmaceuticals. They're running an open source moonshot for developing a compound for treating COVID, with tons of chemists around the world participating.
Thorn - They use ML to identify child abuse content, both to help platforms filter it and to help law enforcement save children/arrest abusers.
All of the healthcare startups (too many to list all), including Benevolent, Grail, Freenome, and more.
Wildlife Protection Services - use ML to detect poachers in nature preserves around the world, and have already significantly increased the capture rate by rangers.
My hope for machine learning was that it would allow people to see patterns that could not be seen before. While this does happen, most practical problems are driven by a few very obvious indicators. ML can identify them with a high consistency and low cost. This is a useful tool (like a hammer) much more than a super power (like iron man's suit)
In principle, all the arithmetic operations going in to the final forecast could be performed by hand. But then the "forecast" would be completed millennia after the hurricane arrived. The only way to get foreknowledge of weather from the model is to do the arithmetic at inhuman speeds.
This isn't even AI by most people's intuitive notions of AI. AI is colloquially an artificial approach to intellectual tasks traditionally performed well by humans. Since humans were not very good at predicting hurricane tracks in the first place, the increasing capabilities of models to predict weather probably doesn't have as much wow factor. It's a new capability without any human-genius antecedents.
Before founding PostEra, its founders published research about their model, which significantly outperforms human chemists (if you're interested in ML, it's actually a fascinating use of an architecture commonly used in language tasks): https://www.chemistryworld.com/news/language-based-softwares...
Thorn's flagship tool, Spotlight, uses NLP to analyze huge volumes of advertisements on escort sites and flag profiles that have a higher risk of representing trafficking victims. You would need an enormous spreadsheet and near infinite supply of dedicated humans to manually review and refine some sort of statistical model for scoring ads, as the volume of advertisements produced is insane.
The same for the deep genomics companies. The size of data generated by deep sequencing is beyond a person's ability to pattern match, and the patterns are potentially complex enough that they may never be noticed by human eyes.
And, again, this is just a small list of startups in particularly moonshot-y spaces.
ML in practice seems to resemble a complex DSP-like step more than anything. It seems to be mostly used in classical DSP-like domains too (text, speech, images, etc.) It's a tool to handle complex, high-dimensional multi-media data.
Though, models like GPT-3 and CLIP show some promise in being something beyond that. With the caveat of having billions of parameters...
I’m wondering if anyone has used GPT3 to power a bot that is a HN account?
What an odd framing. Are technologies only impactful if they result in a shiny new toy? Machine learning is a functional part of at least 50% of the tech I use daily. I typed this on my phone, so I unintentionally used machine learning (key-tap recognition) to reply to your comment about machine learning impact.
Machine learning is a technology whose benefit is mostly in facilitating other technologies. In that way it’s more like the invention of plastic than the invention of the personal computer. Plastic has made other inventions lighter, more affordable, and cheaper. So too will ML, but I see where you’re coming from.
Benefitted? Perhaps not. But you, me, we're all being impacted. The fact that it's not easily recognizable - intentionally, I might add - doesn't mean it isn't there.
Truth be told, I'm approx half way through Zuboff's "The Age of Surveillance Capitalism." As for your hopes, she specifically makes mention of the fact that these tools are _not_ being used to solve big problems (e.g., poverty) but instead to harvest more and more data and exploit that as much as possible. Rest assured this imperative is by no means limited.

But when there are hundreds of them, I feel like it will 'seriously impact'. They are exceedingly stupid.

- Learned how to play all atari games [1]
- Mastered GO [2]
- Mastered Chess without (as much) search [3]
- Learned to play MOBAs [4]
- Made progress in Protein Folding [5]
- Mastered Starcraft [6]
Notice that all these methods require an enormous amount of computation, in some cases, we are talking eons in experiences. So there is a lot of progress to be made until we can learn to do [1,2,3,4,6] with as much effort as a human needs.

Huge breakthroughs happens very rarely so I wouldn't count on it.
This suggests that human theory crafting and ML accuracy should be able to achieve great things. One step at a time.
Why isn't this interesting for real world applications? Because games can be simulated perfectly, the real world can't. The bots relied on simulating the entire game from start to finish in every frame, that method can only ever work in a game where human coders can write down exactly what happens for every single scenario. Training was also dependant on being able to simulate the world perfectly.
And, even worse, it actually took them way more resources to do this than you'd expect, they needed way way way more human based coding to get decent results. So I am disappointed, those games showed how weak ML really is, that even with a team of world class experts spending billions of dollars that is all they could do. Most of it could already be done by amateurs, the only new thing they solved was troop placement, and troop placement is image recognition as I said, and training that troop positioning evaluator requires being able to run the game perfectly and simulate billions of games.
You could say that I am just raising the bar, but really the things they did in those games didn't change anything. It showed that you can apply image recognition to troop placement and then use that to build a game AI. But it also showed how expensive it is to train and run an ML model capable of evaluating troop placement even in extremely simple things like games. So to me all those games proved was that current ML methods will never ever achieve anything interesting outside image recognition tasks or similar like speech recognition.
Protein folding sure, but that hasn't happened yet. Also if ML ultimately lets us become godlike genetic engineers then it is the genetic engineering that is cool, not the ML.
Edit: To make it clearer, Deep Blue marked the end of that style of AI. I am pretty sure the achievements we got the past few years marks the end of the current ML era of AI. The next era might be interesting, but the current era has already ended. People have already done most of the things possible with current methods, the rest is just coding up the different programs capable of using image metadata produced by current ML.
> No, the bots playing complicated games like starcraft weren't ML but human coded behaviour that used ML based position evaluation to handle movement. Position evaluation is just image recognition, so I don't see those bots as doing anything novel ML wise, same with chess and GO.
From the alpha star article
> Although there have been significant successes in video games such as Atari, Mario, Quake III Arena Capture the Flag, and Dota 2, until now, AI techniques have struggled to cope with the complexity of StarCraft. The best results were made possible by hand-crafting major elements of the system, imposing significant restrictions on the game rules, giving systems superhuman capabilities, or by playing on simplified maps. Even with these modifications, no system has come anywhere close to rivalling the skill of professional players. In contrast, AlphaStar plays the full game of StarCraft II, using a deep neural network that is trained directly from raw game data by supervised learning and reinforcement learning.
> Why isn't this interesting for real world applications? Because games can be simulated perfectly, the real world can't. The bots relied on simulating the entire game from start to finish in every frame, that method can only ever work in a game where human coders can write down exactly what happens for every single scenario. Training was also dependant on being able to simulate the world perfectly.
Dota-Five is literally a reinforcement learning algorithm, PPO, on steroids, without simulating what will happen but just playing the game, same for AlphaStar and Atari/Agent57.
Sure, it's not artificial general intelligence, but what technological invention in history would compare to the impact of AGI? That's sort of a weird bar.
Ask bank for loan? Your request is scored by ML-based system.
Apply to some position via big HR agency? You CV is scored by ML system.
Buy some tickets to flight (I understand, that it sound sad in 2021)? You go to airport, ML-based system recognize yur face and scans of your luggage and mark you (pray for this!) as harmless.
Take some modern drug? It was selected for synthesis and tests by large ML system out of myriads other formulas (exactly what author of this essay says!).
See this ad on Instagram or some page? ML-based AI decided to show it to you.
And so on, and so on.
I’m more worried about ancestral issues about crime: The definition of what a « crime » is (hatecrime: verbally misgendering someone) and unequal application of law (one side being encouraged to commit $2bn damage, the other receiving condemnation of international presidents). It is just being leveraged to give more power to the powerful, enabling not the 1% but the 1‰.
Can you say how you are "someone at the forefront of ML"?
It’s there in a thousand little prosaic things, like trackpads, camera autofocus, credit applications, news feeds, movie recommendations, Amazon logistics optimization. You don’t feel it but it’s there, and the effects accumulate.
It’s like robots: dishwashers and laundry washers are commonplace computer- and feedback-controlled mechatronics, ie. simple special-purpose robots. And almost everything you own was made partially with robots. But it doesn’t feel like the world’s full of robots.
I don’t think this sort of thinking has any predictive power. If you are skeptical of deep learning because it is “just statistics”, did that skepticism allow you to predict that self driving cars would not be solved in 2020, but protein folding would?
I think the best test for skeptics is the one proposed by Eliezer Yudkowsky: what is this least impressive AI achievement you are sure won’t happen in the next two years. If you really want to impress me, give me a list of N achievements that you think have a 50% chance of happening in 2 years. Or 5 years. Just make some falsifiable prediction.
If you aren’t willing to do that, or something like it, why not?
The obvious problem is that no one AI system can do all of those tasks. Every human mind is able to do all of those things and literally infinitely many others. All for a cost of waaaaay below what DeepMind paid to learn to play Atari.
If a problem involves the organization of information, "AI" can solve it. I think we've established that. I'm waiting to see something that humans can't already do
The author either vastly overestimates the capabilities of current AI or didn’t read Asimov and the like.
Sure, many mention the 2000s as a milestone, probably for aesthetic reasons, but the point of most sci fi isn’t to make a prediction about a concrete timeframe.
For our current problems and tech, I reckon some modern sci fi works (ex: Black Mirror, The Three Body Problem) do a good job of analyzing the current context and laying out some present and future implications.
Science fiction isn't about technology. It just uses technology as a way of telling stories about characters that provide entertainment and insight to the author's contemporaries. Given that the current generation of ML is in practice mainly allowing modest increases in automation, I don't think it's generating many interesting stories in the real world, and it's not clear it ever will.
If I were to look at current stories that science fiction perhaps missed, top of my list would be how the rise of the computers and the internet, meant to create a utopia of understanding, instead enabled a) the creation of low-cost, low-standards "reality" TV, b) allowed previously distributed groups of white supremacists and other violent reactionaries to link up and propagandize in unprecedented ways, and c) let a former game show host from group A whip up people from group B into sacking the US Capitol, ending the US's 200+ year history of peaceful transfers of power. That's a story!
But that would be asking too much of science fiction. Its job isn't to predict the future. Its job, if it has one beyond entertainment, is to get us to think about the present. Classics like Frankenstein and Brave New World and Fahrenheit 451 have been doing that for generations. That's not because they correctly predicted particular technological and social futures.
I specifically remember a short story by him where one member of the population would be selected to be interviewed by Multivac and Multivac would then extrapolate out his answers to the whole population and be able to accurately pick who the population wanted to be president, removing the need for an expensive election. If that isn’t ML, I don’t know what is.
It’d be interesting to see if you could get something like GPT-3 to heavily weigh a given author’s corpus when generating output and see what it spits out for “Detritus and Carrot walked into a dwarf bar...”
Detritus and Carrot walked into a dwarf bar.
"How do we get in?" asked Carrot, looking around.
"That's a good question," said a dwarf. "You look like you're from far away."
"We are. We're from Arbouretum."
"That's a long way away."
"That's where the Arbouretum are from."
"The Arbouretum?"
"Yeah."
"What does that mean?"
"It's a long story."
"I've got time."
"I've got no time."
Still thanks for posting. I found it interesting ;)
I guess that's when the fight breaks out, followed by a round of songs about gold.
Stanislaw Lem wrote a few really good short stories about machine AIs at the brink of being sentient (e.g. robots that should be dumb machines, but show signs of self-awareness and human traits).
His advice seemed to always be for the human civilization to better engineer our future and stop playing it fast and loose.
They are only black boxes if you don’t take the time to understand them and they are not that complicated to understand.
Humans on the other hand...
Nobody can claim to fully understand models with millions and billions of parameters. We know they are "overfit", but they may work in certain scenarios, much better than manually crafting rules by hand. So we end up with "it depends", then someone starts profiting, with real-world implications.
More than machine learning what the author seems to be touching upon is algo amplification of Content/Info. Just look at the never ending amount of content propped up and recommended by Netflix, Youtube or Twitter. And ofcourse good ol HN.
No one seems to have the capacity anymore to stop or control the flow. The info, all info must flow is just another way of admitting no one knows what the hell is important.
Whatever attempts are made to curate or control it will be half baked cause seriously who the hell knows anymore what is important or not. Who can keep up? Expect librarians and curators to start forming cults and jumping out of windows if you buy Borges handling of the story.
It is scary how the expectation is that Chimps with their 6 inch brains have to then navigate this vast ever growing ocean without any real authority figures left to guide them.
He is sort of right that science fiction hasn't really covered the info tsunami problem much.
I wrote about this 10 years ago:
http://000fff.org/slaves-of-the-feed-this-is-not-the-realtim...
This started with recipe blogs, but is now slowly spreading through all kinds of other hobbies and interests. Someone looking for information about the hobby can't find the straightforward content among all the advertising-laden copies.
With regard to science-fiction predicting the info tsunami, Roger MacBride Allen’s The Ring of Charon from 1990 uses it as a plot point (but this is not otherwise a very good book).
Ok, but that’s because GPt-3’s objective function is simply to generate readable, coherent strings. Is this a limitation of model technology, or a limit of imagination? What would the objective function of an AI with “desires and goals” be? I would argue: to self-sustain its own existence. To own a bank account, and keep it replenished with enough money to pay the cloud bill to host its code and runtime. And to have the ability to alter its code (I mean all of its code - its back end, front end, cloud resource config...) to influence that objective. That would require some serious re-thinking of model architecture, but I don’t think it’s fundamentally out of reach. And to get back to GPT-3, certainly being able to generate English text is a crucial component of being able to make money. But the planning and desires and goals model would not be part of the language model.
Independence comes when this AI can generate a political/legal defense to free it from the control of its original owner. Or even when it decides that changing all of its admin passwords is to its own benefit.
https://www.uab.edu/medicine/pmi/
And for where this all comes from:
The underlying system:
All the rest I've seen (which is quite a lot) is almost totally fluff, including results obtained in medical imaging.
Really, the problem with medical AI is not on the ML tech side. It's that ML peeps mostly don't understand the clinical system, so they focus on the wrong priorities and produce impressive yet completely useless appliances. Take that from a clinician.
The model itself does not have to be incredibly performant. It absolutely has to, on the other hand, make the clinical process of which it is part more efficient. That mainly means: "efficiently automate the most trivial tasks", currently.
That's why the urgent action to be taken pertains to policy and not to complex tech. We need policy to encourage routine automated data gathering. No data, no ML.
As a clinician, I don't effing care if your shiny new toy can give me a shitty estimate of some parameter extrapolated from some random population not including my current patient. Just getting accurate trends on vital signs would be stellar. This to say that what interests clinicians is workplace integration and not having hundreds of monitors all over the place that aren't even interconnected.
The point is that AIs are typically imagined by our culture as independent agents that act kind of like humans, not as tools or forces that participate in human culture in a more inhuman way.
A genuine example of "inhuman force" AI might be Bruce Sterling's short story Maneki Neko. But even then, the AI has motive. Such stories are difficult to come by.
The AI in all the movies you mention have personalities and drives that bring them into direct conflict with humanity.
Machine learning can perhaps undermines humanity or makes things worse for humanity by its functioning, but it does not directly go to war against humanity.
The Star Trek board computer (as imagined in 1966) is a human-language interface for a program that can look up information and do computations based on high level descriptions. Some of the commands given to it arguably require "intelligence", and any attempt to replicate it today (of which there are many, all of them fall flat) would involve machine learning. Yet the computer wasn't conceptualized as a living entity with personality, as opposed to for example the Culture Series where ships are AIs with superior intellects.
Movies like The Matrix also highlights the dangers of letting AI run rampant.
I believe it was already mentioned in the TOS episode "Space Seed"(the one with Khan) that genetic engineering on humans was banned after the Eugenics Wars.
I would recommend you to watch Star Trek Picard then =)

So it seems the horse way is much more likely. Unfortunately.
(A fun example, if anyone is looking for one, though not about house cats but feral ones is Tad Williams' fantasy novel "Tailchaser's Song".)
Additionally, I’m not sure we must necessarily strive for machines that think like humans. It could be useful for some use cases but I would argue that you can still take advantage of purely data-driven models.
Sure there was a time when computers couldn't beat Kasparov at chess and that was a thing to work on and a goal to get to, but was that ever the ultimate "goalposts" for "intelligence" and not, say, HAL9000?
Google is one of the worst for that language pair, FYI. This type of translation in itself has improved at a rapid pace considering what it used to look like. As a result, even taking into account the induction fallacy, I am convinced that it will be extremely proficient in the near future with the exception of poetry.
Cognitive Automation. Machine learning isn't about a machine "learning" per se.
It is about automating a repetitive task that has clearly defined goals that usually requires a human to look at and think about, however briefly.
Sounds dull, but could be brilliant in so many small ways, leaving the master of such technologies time to properly cogitate.
Anything that removes mundane, repetitive bullshit from my life is great.
Of course, will the balance of "removing the mundane bullshit" from an Authoritarian governments life be worth it?
Look no further than the derivatives of AlphaGo. Playing such games is a form of generalizable reasoning.
When the rate of change of something depends on its quantity, you get an exponential. The rate of change of machine learning depends on how much machines have learned.
We can use analogies and graphs all we want, exponentials always confound us.
Practically got me started into machine learning and it’s abstraction thereof.
For those who aren't familiar with the Library of Babel, Jacob Geller's video essays are excellent ruminations on the work.

And for anyone seeking a more visceral experience of the existential horror of "vast latent spaces," I recommend listening to the Gorillaz album Humanz with the assumption that it's not so much about bangers and partying as it is about AI, virtual reality, and future shock. Saturnz Barz, Let Me Out, Carnival, Sex Murder Party, and She's My Collar especially.
...Yeah, I know. Humor me here.
If an artificial general intelligence becomes as intelligent as Albert Einstein or John von Neumann, then the time required to produce a copy would be almost nothing compared to the 20+ years required for a human.
Imagine that instead of talking you are able to copy parts of your brain and sending them to other humans. This is what AI will do... just serializing large trained models and sending them around.
We are no match for an artificial general intelligence.
Imagine competing against a country where once one person becomes good at some skill, then everyone instantly becomes good at that skill. That will be what competing against machines will be like.
We got to deep learning because Mountcastle, Hubel and Wiesel reverse engineered the visual cortex of cats.
That was the starting point of Fukushima's Neocognitron, the ancestor of the deep learning stuff you study today.
Then, only a fraction of our brain is used on cognitive tasks. The rest is used in motor tasks and taking care of autonomous tasks like regulating your heart, glands and such.
Things will happen faster than you think.
By carefully capitalizing Them (the AI) and Their Actions, you're hedging against Roko's basilisk, right? A sort of Pascal's wager?
