A new way to predict when software jobs will become automated

This is really optimistic and completely overlooks the 80/20 problems that have plagued both AI automation and traditional automation. The AI sweeps up the easy cases and humans are left to fix, or paper over with heuristics, the remainder.
Example? Speech-to-text. It's pretty good and the spread of automated closed captions to youtube videos is a definite benefit. But broadcast TV will almost exclusively use human subtitlers still, because the last few percent of accuracy isn't there.
Software hasn't even effectively been reliably outsourced to cheap humans yet. Perhaps you can automate some of the production of CRUD tools, in the absence of a better framework for them (frameworks, compilers, libraries and npm should all be thought of as forms of automation). But anything with a competitive advantage will be relying on humans for a long time.
And same will happen to development. Lots of tasks will be automated and less people will be needed as a result.
Take it a few more steps and then you get to automated analysis tools, system simulations, and NLP systems. This looks essentially like IronMan's Jarvis running heuristics interactively.
"Which edge cases did you cover?"
`I covered 3000 edge cases extrapolated from these bug reports...`
It may be that this training will need to get pushed to the education system (whatever that looks like by that point).
Additionally, there can be a mentorship model where the junior performs the first pass of reviews and iterations before presenting to the senior.
Think Star Trek: how does anyone learn to fly a spaceship? Lots of simulation and running smaller parts of the system in close observation... which isn't too different from now.
I’ve also seen a superb one at Decathlon stores in Poland. You dump your items in a box. It automagically scans everything using something that I’m guessing is RFID based. Bag, swipe a card to pay, and goIt is much simpler to use and is actually pleasant. It’s one step short of just walking out of the store without actually checking out.
It is already happening. For example; setting up a production DB in primary-secondary mode; with daily back up and what not used to be quite a bit of manual grunt work. AWS Aurora and similar services handle 70-80% of the pain leaving you with setting up right table, index etc., Same in setting up a backend stack with DNS, load balancer etc.,
My guess is cloud services will automate even DB configuration. They have 100% visibility into the true production load pattern they will be able to suggest or even auto-configure things such as indexes.
That said, we will continue to have a need for dedicated dev-ops team. Just that instead of say 10 people team it'd require 2 person team. But you still need a person dedicated (maybe part time) baby-sitting infrastructure. Don't let every dev get their hands on infra.
As a side note, we were told decades ago that visual programming would similarly displace developers; however, I'm doing perfectly fine
It may not be true automation, but it's very effective, and it's something we're seeing not only at the grocery store. What used to involve calling a person up and asking for services is now done through web portals... taking a few minutes of the person's time.
The real issue in this degradation of customer service is usually not the time cost but the fact that, while it doesn't change the amount of random human error that occurs, it shifts the penalties onto the users... if your travel agent screws up, you get a refund... if you screw up (in something that used to be someone else's job) you're told to eat the costs.
Thing is, the replacement of a process when an ersatz alternative may not be "true automation" but it doesn't need to be in order to work. And job destruction across an industry isn't 0/1. There are still jobs in car factories in Detroit, just far fewer of them. There will still be jobs for truck drivers in 2040, but there probably won't be nearly as many. Employers will still need programmers; they might not need the same number of us. It only takes a dip of a few percent in job supply to cause wages and working conditions to crater (that's inelasticity), and even this says nothing about the ripple effects and systemic calamities (up to and including the possibility of economic depressions that last decades) that occur when large numbers of working people lose substantial income.
In some cases, shifting work to the customer is a net positive, especially if the customer can estimate their own time and effort better than they can estimate and manage someone else doing it. Nearly a half century after The Mythical Man Month, managing software development is still widely agreed to be an unsolved problem.
The cost of software development is not just the time and effort, but the existential risk to your own job or business from its unpredictability. This is why I do all of my own programming, and also most of my own home repairs... and use the self checkout at the supermarket.
It didn't displace developers because the industry has grown to absorb them. In my own case, I use my programs to get my own job done, then hand the whole thing over to the project team, and the developers write the production code that ends up in the product... but not at my expense.
The scenario in which demand for labor drops massively but human labor is still needed. Many industries would lose 80% of workers, but 20% would remain. Those 20% would be very high status and well paid, at least compared to the UBI neo-serf class that yheir former colleagues of the 80% have fallen off into. It is yhese 20% that woll form a new upper middle class. They will be isolated from the UBI serfs and live in gated communities.
These communities won’t be like the extremely luxurious communities of the one percent, but still isolated from the poor.
In another thread on this topic I’ve predicted a rise of technologically driven authoritarianism where the human elite uses AI to oppress the poor. The 20% that maintain such a system’s infrastructure (technical and otherwise) would probably support it politically. In most right wing authoritarian states the government has drawn support from its upper middle class. In left wing authoritarian states like the Soviet Onion there was a vast beurocrat class that was structurally isomorphic to the upper middle class.
I’m predicting that the humans that hold onto their jobs the longest, and work in high paying stem jobs, will form the core of such a regime. This is good news for many HN users, because you’ll be part of those 20%. I’m just worried what happens to the people that aren’t so lucky.
Of course there are caveats here that the automation may not happen soon, happen quickly or lead to societal upheaval or fascism, but all of those are still possible.
Your crisis has been added to the queue and will be dealt with in due course. Your crisis is .. <click> 1,734 in the crisis queue.
(seriously I think this is best left alone until it clarifies or subsumed into the general "regulation of harmful doing things with computers", like privacy laws. Self-driving cars are their own game and deserve immediate scrutiny.)
Once we reached AGI, there is no way to back out of it and say we don't want it, because now other countries will also have AGI. And there won't be overnight solution to deal with the overnight crisis AGI created.
How many decades is "overnight" supposed to represent here? Or do you really mean overnight? The WarGames scenario where the AI decides the only logical option is a pre-emptive nuclear strike?
Collapses, even in seriously banana republic countries, do not happen overnight. They are slow and agonising, and present options for .. kinetic solutions.
Oh sweet child. You think too much of humanity as a whole.
If what you said was true, all countries would have had an equivalent of TSMC to begin with. At the very least, every country would have had multiple supply chains for anything they deemed of strategic value. Each country would manufacture cars, computers, commodities.
But instead, it’s all outsourced to a player who they think is the best. So if one day some anomaly happens and there is a new sea where China used to be, at least a lot of Europe and North America is going to be screwed big time.
Same with AGI. It’s going to happen at one company in one country. Not only will outsource their AI needs to that company, but its home country is going to have a leverage on all of it, but lurk in the shadows most of the time.
And once everyone else is dependent on HAL, should it, say, commit suicide as in that Asimov story, all countries that signed up are going to be fucked.
That is the problem with GAN generated art. It is pretty good but then you don't have a psd to modify it so it is useless for most purposes.
But hey, we got code generated in 5 minutes. Can't bugfix it tho...
Why would an AI writing assembly give it an advantage?
> Also software engineers are expensive. Corporate greed will drive this faster.
Are they? You can get a software engineer for less than $10,000/year.
When I was going to university in the mid-00s I had quite a few "advisors" recommend against going into computer science, because corporate greed meant all the jobs were going to be outsourced and US salaries would tank as a result.
There are lots of non-human-optimized options that aren't raw assembly. Any intermediate representation, for one (e.g. LLVM IR, C-- used by ghc, Python/JVM bytecode, abstract syntax trees to simplify parsing).
And even raw assembly is often not what the CPU operates directly on (see: microcode).
One of two things tends to happen.
1) The 20 is a fundamentally different problem, but is itself solved by applying different new developments (e.g. most breakthrough devices: semiconductor manufacture and design, cellular phones, iPhone)
2) The 80 is so useful that work realigns to avoid / ignore the 20 (e.g. most mass market adoptions: horse drawn carriages, trains, automobiles, planes, television, personal and business computing)
The key thing realistic futurists harp on is what drives revolutions is superior utility versus the status quo.
If AI is "same as human, without the labor costs," it will be adopted gradually. If AI is "better than human in a fundamental way," it will be adopted overnight.
I mean, go get drunk and pass out on the back of your horse and the chances are real good it’s going to take you home without running into the back of a parked emergency vehicle sitting on the side of the road without giving it specific directions to do so.
Full disclosure: I’ve never passed out on a horse…
"A horse for every person" probably wasn't the best of times.
On the other hand, they are excellent listeners.
We're not going to see AIs replacing humans in all jobs any time soon. We are going to see, barring regulation or (better yet) a total overthrow of the corporate system, increasing power accruing to capital--due to AIs' ability to perform the "80" in the aforementioned 80/20 analysis--with devastating human consequences. And this is true even though DALL-E, in the given example, doesn't actually understand (even in a figurative sense) that a third of Africa is desert or that certain facial expressions indicate concentration.
If an AI can do even half of your job--and anything you do as a subordinate probably can, in principle, be done by machines--you should be terrified. You're not going to be working 20 hours per week; you're going to be working for pennies due to wage inelasticity--there's now twice as much competition for jobs. Automation is of course both desirable and inevitable, but we've got to transition to an economic system in which it doesn't result in widespread poverty and homelessness... which is not the one we've got right now.
Are there any examples of this and how would we qualify them? Do plenty of pedestrian control systems also satisfy that criterion? After all, the SpaceX landing system is a feat of piloting that would probably be impossible for a human , but I don't believe the system is "AI" rather than an extremely well tuned more conventional thing of Kalman filters and feedback loops.
The jobs that it will replace will be the entry level jobs. It will replace the jobs where excellence is not required. It will replace the jobs where quantity matters more than quality. These are the jobs that everyone starts at. Some people learn and grow and become experts. And some remain at some lower level for their whole career. This works well when there is enough work to go around. When AI replaces the need for low-end professionals, where will experts learn their trade?
When combustion engines replaced horses in many applications, they did not eliminate all horse handling jobs. There were just significantly fewer horse handling jobs left.
This also widely varies by language. Automated Japanese subtitles on YouTube are completely useless. Even with someone speaking clearly you'll find at least 2-3 mistakes every line of dialogue and if they speak slightly quickly then all bets are off (it also makes mistakes that seem strange -- Japanese has a very limited set of phonemes so consistently guessing the wrong ones seems very strange).
Luckily the industry has found a way to compensate for this by building the common CRUD app in React and Microservices, so now it takes 3x longer again and requires twice the staff to maintain it.
precisely. or like with aws, what used to be a sysadmin is now two to three devops engineers doing the same stuff. if anything ai will enable even more people to get into software dev and thus allow even more businesses to thrive and thus create more jobs. ais and tools like you mentioned are like fertilisers. the more crap the more jobs for us.
As someone working in security I'm not very worried about career prospects. There is plenty of time to point out crap yet...
You could have a setup like the Socratic Models paper where the code AI talks to the language model AI which is fine tuned on facts about the business context.
I just don’t know how far out we are from that. Someone at Deepmind, OpenAI or Salesforce (Salesforce have their own code AI research unit that few people know about) should work on this.
If someone reading this has a background in economics I’d like to hear what they have to say about this. In all these discussions on this topic I never see anyone bring up economics or empirical economics papers.
"OpenAI estimates that OpenAI Codex (what powers Github’s Copilot) can already complete 37% of coding tasks."
And who decides the task is done, complete and works? The Meat does [2]...The Meat and nobody else.

I disagree with the response to objection 1. Look for more than a few moments at the right side picture and the shadows of the chess pieces are low quality, the shadows continue off the table, and the checkers on the board look more like backgammon than chess. The AI generated sites that clutter google are easily identified as low quality GPT 3 nonsense.
I’d also disagree that the AI “understands” the physics of the sun, or that Africa has a lot of desert. The prompt includes the desert, so it pulls from pictures of the desert. It doesn’t understand that people have a face when they concentrate either, it finds a picture of someone playing chess then maps an “African fortune teller” onto that person. Oh, it also has to grab photos of an African fortune teller. The AIs used as examples in this article (DALLE, Copilot) are regurgitated humans. What happens when we have new tasks that we can’t train on? They don’t “understand” things, they recreate them.
Maybe I’m just typically bad at estimating the exponential growth. I’m not optimistic I can replace humans with Copilot authored pull requests anytime soon. It might be good at “write a function to convert ISO date time to MM/DD/YYYY” but we’re decades off of “create an API for managing a warehouses inventory.” Either way, being replaced by copilot would require business partners to be able to explain what they want, so I’m not worried.
20+ years later, search sucks because it’s mostly robots (or humans acting like robots) writing SEO centric copy to capture valuable queries.
Most of these strikingly capable “AI” tools today like DALL-E and Codex are fundamentally built by applying more leverage in new ways to a corpus of human work: art/code/etc.
What happens if these systems take over and 99% of the humans stop writing code or making art and successive systems are trained on mostly regurgitated AI output?
The same effect is apparent in equities: index funds now make up the bulk of investment, but they merely follow other money flows in lock step, many of them driven by computers. As a result the decisions of a relatively small number of actual humans have incredibly outsized impact on markets.
We will have a system of infinitely recursive navel-gazing that is devoid of utility once the actual intelligence that was the key driver of the system has dried up because it’s economic value was captured by greedy hill-climbing algorithms.
Pieces like this are naive because they extrapolate what they see as trends without recognizing that the world is a dynamic system. Predictions are never this simple when the subject is so dependent on the state of the world which it will dramatically change.
But what happens when AI needs less and less "real" data for training then it, will not degrade like google's search, which by the way is still the best from all the search engines I have known and tried.
What is intelligence? Can classical machines become intelligent, or is there some mystical quantum quality involved? Is there a limit to intelligence? What is the best form of intelligence (single entity vs society), Is intelligence even understandable, and therefore engineerable? Are current neural networks in any way intelligent (they seem extremely good at pattern matching, and/or regurgitating those patterns, but beyond that I'm not sure). Etc, etc, etc, etc.
From the outside we've experienced exponential improvements in ML models, sure. But those didn't come out of nowhere. They are powered by massive efforts involving humans.
Personally I'm not worried about losing my dev job to machines in my lifetime.
What about the ripples from “enough people” losing their jobs?
Covid and the logistics whiplash have done nothing to embed in people they’re just one of seven billion. Each still acts like the king of their own mountain. It’s pretty sad.
You have no say over your place in a future society that appears keen to rug pull the masses lives from under them.
With writing and graphic design less so. The best AI can do is to generate a text or image that it judges itself as passing as realistic according to its own model.
For jobs where passing a being realistic is good enough I certainly see those as being replaceable.
This might include mundane coding tasks like writing an API to an existing server.
Tasks where the goal is not closed ended, where the computer cannot judge itself if it got the correct result and passing as realistic is not enough, might never get replaced by machines.
I don't buy that devs are going to run out of things to do. Instead I see this increasing the leverage of engineers (who are really just creative problem solvers) such that an exponentially increasing number of lower value problems will make financial sense to solve with engineers.
I think we'll see the same thing with designers and all different kinds of tech workers.
Pay will increase, not decrease (at least globally) because business people don't have the training to work these levers or judge the quality of the output.

Programming is completely another deal, it is a creative task sure but once you get it wrong it is a costly mess! Another point is that most of the difficulty is not even actually coding but understanding what to code from people that cannot express what they want...
So yes I agree with this statement, AI would probably not fully replace the coding workforce but would help with some careful supervision.
Meanwhile, the resultant code or 'solution' is also not a solution in a vacuum - it needs to work within certain workflows, tooling, skills, cultures, processes, orgs etc...which are also often undefined, dynamic and irrational.
Not saying AI can't help in many areas, but do the areas which are growing exponentially as described by OP help AI function effectively in enviros such as the above?
What about the argument that unless the collective gets better/smarter, that AI will indeed only be as smart as the current collective? Perhaps this is the "AI will hit a ceiling", but it needs to be trained on something. If more and more gets automated in these areas, how will they ever improve?
This says to me that the future programmer will be closer to a software architect. Someone that can interpret what someone wants and decide what the solution is using all the resources available including AI tools. Not all programmers can do that. I've known plenty of programmers that are great at their job but lack social skills. Those are the type that will definitely be affected by AI. Given that you don't need 100% perfection in AI to make an impact in the industry and programming jobs then I see big changes happening with-in the next 10 years at most.
Don't believe it? Look at Dall-e 2. It won't get rid of designers or such but many people will start to use it in some cases and by-pass the designer all together. Also a new crop of designers will use Dall-e 2 to create some of their work. Those that won't will be left behind.
Designers today, programmers next... Yes!
1) Cyc and reasoning - stuck for decades but making slow progress
2) GANNs - can detect a whole lot of things by being trained on data
3) MTCS - this is AlphaGo and AlphaZero. Adversarial networks that play each other. Have nearly solved any turn based game that can be expressed this way, and can be used for StarCraft etc.
4) Data fitting - can get scientific data and find new scientific theories and formulas to explain them, etc. by essentially building analytic functions from building blocks and optimizing for simplicity.
5) GPT3 and DALL-E - have very little understanding of anything, they just throw a lot of bullshit at a wall and see if it sticks. But since the bullshit is actually stitched from all serious human output that could be digitized, they sound quite serious at times (even though they show total lack of understanding when basic math is involved for instance, as numbers get higher).
Now I will be willing to admit (and have written about this) that logic and science may be a “poor man’s” million-dimensional vector data fitting. Maybe our binary logic and simple models are the thing that models the world worse than the million-vector models that capture the actual dynamics better. But humans won’t be able to understand these dynamics any more than a cat can understand most of your activities based on abstract systems.
All that other stuff — superhuman sensors, motors etc. gives them unfair advantages, like the finger on Geopardy. Auto-aim and self-driving cars are more about HUMANS improving, training, and then downloading the new software to every device.
What scares me most, though, is deepfakes and swarming. You don’t need GREAT AI to take over political discussions, or direct swarms of self driving cars or drones to wreak havoc. Online, swarms of sleeper bots can inftrate many communities and execute sybil attacks at scale. They can amass karma right here on HN with comments stitched through bullshit that sounds just like HN. It’s a positive EV strategy for the swarm. Eventually they can edge out all human participants where everything you see all day long is bots.
The kicker is THEY DONT NEED TO PASS THE TURING TEST in order to take over our systems because most people consume content non-interactively (read comments, watch videos) . “Truth” online is just a correlation of A vs B and every repository of “truth” can be flooded with a different correlation. Stephen Colbert fans even did it manually with elephants tripling in Africa! Imagine what botswarms can do to out sense of truth or political will or anything!
This. If an AI does take over the world it will be as a cult leader, with the willing help of millions of humans who've "done their own research" on youtube. The AI will of course be at the top of all search rankings and auto-suggestions by other "AI"s; that's table stakes for that kind of scenario.
Buzz off.
That aside, I'm not sure how impressive is an AI that could do 37% of "all coding tasks". It's like a self-driving car that only works 37% of the time.
What are you trying to pull?
I regret mis-quoting TFA by an article, because if I cited it correctly I’d really lay the fucking smack down here.
Have I adequately answered your condescending question?
One of my tasks as a software engineer is to reduce code as much as possible. Because code is a liability, it needs to be supported, maintained, adapted, ported, etc, etc. If you can do same or more with less code, please do. If you can reduce other's code, which is often legacy code, please, do.
Right now all demoes I see are generating code, they do not changing code, not deleting something. This means the only way for text-to-code system to get a new program for a changing requirement is to regenerate new code from scratch.
I am not in the mood of deducing what that means for AI, it is enough for me to know what that means for typical software development process.
From what I understand most intensive AI tasks require using a GPU and the leader in the GPU business is NVIDIA. Looking at their profit margins I don’t see any drop in fact a growth of over 30% yoy [1]
Also as an aside, I am a big skeptic of ARK. During the short time she had a diva status Woods seems to have been more lucky than good. That said, investing is a long game.

"design and implement a SasS product that humans will give you money for" is a much less well-defined problem.
applying AI to boilerplate will probably be effective, but that might just eliminate more outsourcing and allow local devs to be more productive, as an extension of IDEs that have various macros to reduce boilerplate.
i think getting past that to the point where some manager can just ask an AI to design a commercially viable SaaS website top to bottom and it plonks out of the machine is exponentially more _difficult_ of a problem domain.
although a lot of the websites which pollute search results in google will be churned out by the millions and millions.
Now SaaS is one thing, but who would trust industrial control software for AI. At least current one. Here is oil refinery, make money. Oh, take these bank details as well and go figure it out...
If there is enough work doable by AI, why would humans still be needed? Some humans would cover the missing 10% of what AI can't do, as pointed out in other threads. But that leaves a lot of humans idle.
The entities operating this AI would still need to operate i.e. in a country. So the country's government will have to enact some sort of legislation to regulate the AI's impact.
It doesn't necessarily mean everybody will be out of a job and miserable. Probably work would be optional and shelter, food and the likes would be provided by the government.
There's many jobs that AI will probably replace. Software will be among the last.
The nature of our work exposes to new technological developments first, so we’re also the first to talk about this AI. If I went on an art forum I might find posts by artists worried about Dall-E but those posts wouldn’t come about until later when the artists hear about this technology.
Programming was automated 65 years ago.
The "Formula Translating System" introduced in 1957 eliminated the drudgery of programming by allowing users to simply enter equations into a computer directly.
Specifying machine instructions and memory addresses by hand rapidly became a thing of the past.
Today, having a programming assistant is as quaint as a secretary.
Personally I can't wait to be made obsolete by the god AI.
The limit to human creativity would move from a technical one to your imagination.
... and the fun part with a logistic curve is guessing how far up you actually are...
The discussion about AI always focuses on replacing the leaves of the trees in corporate heirarchies, but the value obtained by replacing the root seems to be much higher.
One could also plausible replace shareholders with AI, although then one might start to question the whole structure of investment capitalism... maybe AI would be better at making long-term decisions about the distribution of capital to prospective business operations than some group of Wall Street funds are?
Perhaps we'll see AI-managed pension funds in the near future with significantly better results (and more interest in the long-term health of the outfits they invest in) soon?
I don’t know which is worse, an amoral corporation using AI to crush its workers or an independent AI working for its own interests
However, I would notice that we have been blessed with a different exponential, which we have been riding into the future. That is the exponential of processor speed and storage and all of the other computing resources. It's a perennial observation that our actual programs have not gotten much faster. The extra resources are immediately wasted. The reputation of hiring developers from developing countries, the cheap foreign labor force, for us has always been that you get a big ball of mud which you cannot maintain very easily. I do not see AI helping with this, but rather exacerbating it. Beforehand, there was a reasonable limit to how many lines of code you might expect from a developer per day, maybe a couple hundred if they test their code well and do other things to refactor and simplify. But with AI you could imagine it multiplying 10-fold, just throw more mud at the problem, the mud ball is already huge: what could it hurt.
In fact, we may see the Smalltalk revolution! Of course this has been prophecied before, but never really come to pass. In this more-dystopian form, the idea is that everyone leans heavily into AI and something like kubernetes for modularization. Every single cell, every pod, in these gigantic supercomputer clusters which shall exists to serve up a smallish blog, needs to do something small enough that with its abundant AI generated code, it can nevertheless live and die successfully, spawning new processes as needed. The blog is thousands of small mud balls, and they work together in signaling pathways that are no longer understood by any human who works on the blog, and the dominant metaphor ceases to be one of mechanism and design and inputs and outputs... Rather it is biological, or even ecological. To start such systems up requires a story of “childhood” where a harness coordinates the first thousand nanoservicesv and grows the cluster into a template for the living application, then it needs AI-style “training” to reconfigure itself to handle actual business purposes, finally it will be released on the world, only to make mistakes which we will have to educate it to discern as mistakes... We certainly can't fix the system, we don't know how it works. Not what Alan Kay envisioned! But who knows. Maybe our kubernetes clusters will go to school one day.
This era would be built on several basic principles. The first one is that you would have no real separation between source code in some text editor, and the running program—a prophecy that has yet to come to pass. All the rest of us rely on shooting a misbehaving program in the head and birthing a similar child with slightly altered DNA to replace it... Smalltalk expects you to have a conversation with the program as it runs: the whole programming language is instrumented with reflection, and every module is hot reloadable. There is literally a method, Object.become, “OK computer, take all of the references anyone has pointing to that other object and point them to me, I will be taking over for it.” Bold.
A second conceit is that the new way to be a programmer, the new metaphor, is not one of traditional authoritarianism—think in particular of remote procedure calls. But the new metaphor will be biological: a module will peek around its environment, maintain a “homeostasis” of inner state consistency, the system as a whole will be tolerant of intra-module logical inconsistency, while the individual cells will just die if they cannot maintain consistent state, cells live, cells die, cells organize into larger tissues and organelles and organs in order to find their greater purpose.
A third great principle is fractal architecture, the idea that the parts should contain the essence of the whole. So in functional programming you might build a computer program out of parts that are not computer programs. But Smalltalk wants to say, no: every computer program in this language will be constructed out of units that are fully fledged computers in their own right, running one or many computer programs. And so there is no need for all of these computers to be on the exact same host machine, of course they can be because a computer can pretend to be multiple computers by task scheduling, but it is not necessary.
Related to that, there is a vast skepticism towards locking and atomicity. Implement virtual time, or leverage the full power of the actor model... Those are preferable.
