hashxyz··on Why every Rust crate feels like a research paper on abstraction
The article is okay, but the writing is bad chatgpt. Em-dashes in almost every sentence instead of commas. Out of place analogies and metaphors which barely make sense. Randomly sprinkled slang for an audience of teenage redditors.

hashxyz··on Finite Field Assembly: A Language for Emulating GPUs on CPU
Pretty sure this is just vectorization. You can pack some 8bit ints into a machine-length 32bit int and add them together, that is vectorization.
hashxyz··on OpenAI Fails to Deliver Opt-Out System for Photographers
Can you back that up with anything? I’ve gotten this as a vague sense, but it seems hard to find much actual background about how he manages to continuously fail upward.
hashxyz··on Formal Methods: Just Good Engineering Practice? (2024)
I don’t see how the distinction makes any sense when the Verus project you linked requires you to write correctness specs. It sounded like intrinsic techniques were preferred because they would not require you to write and maintain a separate spec, but this is not the case.
hashxyz··on A Devil's Bargain with OpenAI
I wonder if there's another reason for Sam brokering deals with lots of major news outlet. Surely OpenAI won't try to exert any type of editorial control over these publications. That would be absurd!

The workload they have is already optimized for something like an Nvidia GPU.

AMD will succeed at this as long as they keep it together.
hashxyz··on Sam Altman Seeks Trillions of Dollars to Reshape Business of Chips and AI
This is not going to age well. The current round of AI accelerators are going to flop hard because there is a deep hardware software mismatch. All the accelerators target GEMM and CONV, and get bottlenecked when most of the other extremely common tensor operators get mixed in. It turns out that Nvidia GPUs are already pretty close to the ideal type of chip you need to execute models people actually want to use.

Nobody in the AI chip hypespace seems to understand this, it’s just stupid money running around trying to eat Nvidia’s margins. Sam Altman understands this less than plenty of people.

It’s becoming harder for me to see him as anything besides someone who is very talented at growing power, but not much else. Perhaps he will succeed in misallocating a trillion dollars along the way.

hashxyz··on To Save the Planet, Should We Be Moving Slower?
So basically the balancing point at which CO2-based heating stops is bounded by this 155K number, which I’m assuming relates to something really hot and bad on the surface. This means that with just this model we will all die.

Can we not just seed clouds to reflect lots of energy back into space though? Maybe that is a stupid idea, but I could come up with 10 ideas like that and maybe someone could come up with an idea like that, but which actually works.

hashxyz··on To Save the Planet, Should We Be Moving Slower?
This makes sense and gives me some things to learn about, I really appreciate it.

If climate science is correct, the one hole I still see is that it doesn’t take into account future improvement in technology, which I think might have some solutions especially when the problem actually threatens an economic player like a 1trillion dollar company. It is basically a choice to believe something good like this can/will happen, so you could call this out as semi religious.

Thank you for engaging with me in the end.

> you can surely list reputable studies

Dude neither of us have ever read a scientific study about climate change. We are both going on bullshit we read online and related to experiences we had in corporate land. Maybe I read more right-leaning stuff so I have a more counter opinion. Don’t pretend any of us are fact checking the magical climate science, we aren’t.

The one thing I actually have firsthand experience with is computational complexity. And after thinking about it for a while, it seems plausible to me that we cannot know the scientific prescriptions we see in negative climate coverage with nearly the definitiveness that they claim.

And it also seems plausible that a lot of people gradually managed to form a doom and gloom committee to find doom and gloom in a noisy world where there aren’t that many definitive answers.

> Who recommends turning off capitalism

The article is about degrowth.

The paperclip thought experiment is a stupid thought experiment. An AI that had the executive functioning to improve its entire substrate (e.g. rewrite the entire TSMC Nvidia chip and software supply chain) would require the same higher order agency that would stop it from destroying the world to turn it into paperclips. It only seems plausible if you spend all your time disembodied from reality browsing lesswrong.

> That time is now

We diverge on this point and I talked about it in other comments.

> we should decrease our current CO2 usage as much as we can, even at a small price of personal luxury

It’s luxury because we live in the first world. In the 3rd world where most people live (and most people are poor), these policies have catastrophic consequences, such as the Sri Lankan organic farming affair.

hashxyz··on To Save the Planet, Should We Be Moving Slower?
I’m sorry man but based on the stuff I’ve worked on and the situations I’ve seen, it just seems more plausible to me that the scientific enterprise tasked with scaring the shit out of everyone is not sampling and unbiased distribution.

I agree with some of your points about excesses of American lifestyle (where I live), but there is another side to this. A pretty good proxy for wealth is basically how much stuff you can waste and not care about. I can leave all the lights on in my house because electricity is cheap, or I can afford to eat so much delicious food I become overweight and get heart disease.

You could argue that I should turn off the lights, and on that point you might have some ground. But more generally there are many things in my life that I save time on by basically throwing a little money in the trash, and I am very fortunate to have this opportunity. This is on a spectrum and we should obviously not cause obscene long term damage so I can save 2 seconds per day, but we are not at that point yet.

And regarding inequality, it is also on a spectrum, and at some point it is definitely too much, but I don’t think we have necessarily crossed that line. 99% of the people in my city have enough food to eat. And the right amount of inequality is certainly not 0, the only way to achieve that is by killing all life on earth. Some inequality is a natural consequence of the different branches of possibility that people explore with their lives. To the extent that we have anything in our society it’s because we are able to share ideas and cooperate. A society will necessarily always have the have’s and the have-not’s.

> I would suggest that we can do better by not going there

The problem is that you are recommending we turn off capitalism, which will have serious consequences that are easier to predict than climate change: we will doom the world’s poor people to lives of certain poverty with no hope of upward mobility.

hashxyz··on To Save the Planet, Should We Be Moving Slower?
I agree with your last statement, although it is describing a very simple interaction and I don’t feel certain that we are observing that in action yet. I also don’t know if there are counter-balancing interactions that we aren’t aware of yet.

If humanity does end up accidentally terraforming the planet to get to hot in a positive feedback loop, I believe we will be within a line-of-sight to terraforming it back in the other direction.

Technology has solved all our physical problems so far. Maybe we will seed clouds in the upper atmosphere to reflect a lot of energy back into space. Maybe we will find something useful to do with captured carbon (which doesn’t just release it). It is insane to suggest capitalism won’t solve this problem by the time it actually needs solving, and therefore needs to be shut down (it’s the thing that actually works).

Your entire framing of the world is engineered by pessimistic news articles which only tell a small part of the story.

Is loss of biodiversity bad? Maybe. Will we have resurrected most extinct species using jurassic park DNA within the next 500 years? I dunno but if that happened, it would make the current loss of biodiversity into more of a blip than an apocalyptic thing.

The science and technology enterprise is economically motivated. It is pretty good at creating value out of fewer and fewer resources. It is not good at making godlike insights into the far future about the late stage interactions between itself and the physical world. Any definite predictions provided to you are more likely driven by short-term incentives of some political figures.

There is nothing indicating massive wars are coming due to climate change, most of the world is lifting out of poverty not slipping back into it. If the world does heat by 5-10 degrees, we should be focused on making sure indians and africans have enough economic resources to afford air conditioning like we do in rich countries.

hashxyz··on To Save the Planet, Should We Be Moving Slower?
Do you even know how many years “an earth’s worth of biomass” could power our civilization? What if it’s like 1,000 years? I think you are just doomposting.
hashxyz··on To Save the Planet, Should We Be Moving Slower?
What if you actually can’t predict the future and climate change is actually good? What if having kids is actually a great thing for them and for the world? These are reasonable ideas if you don’t just spend your time doomscrolling on twitter all day.

People talk about the AI singularity but the whole world is a singularity all the time. To model the entire world and predict how everything is going to play out on a social and economic level is obviously impossible. To make impoverishing top-down prescriptions based on that seems criminal. To utilize this storyline as a political mechanism is cruel.

hashxyz··on To Save the Planet, Should We Be Moving Slower?
I am getting sick of seeing the same edgy fatalistic comments every time a climate article is posted. If you are really such a master of the universe that you can predict the future and know it’s gonna be so horrible, then you must also know that the only morally justifiable action for you to take is to end your life right away to become a net-zero hero.

Otherwise why don’t you calm down and entertain the thought that maybe the future won’t suck, and might even be normal or good, just like the present is right now.

Why are you working on technology if you don’t think the future will be great?

hashxyz··on I don’t want to be an internet person
That story is about a fake-cancellation that Charlie created with his friends against himself. It is some kind of commentary on this very situation of you trying to get this taken down.

I wish everyone saw it this way
hashxyz··on Ask HN: I want to start a company, but I am currently overemployed
Most of my employment agreements have signed away all work I do all the time. I am in CA so this is apparently unenforceable, but not a good situation to be in. If I had known before I would have asked for adjusted contracts that weren't so strict about what I do in my free time, but I didn't know the minefield I was getting into. Probably I can work to replace the current positions with new ones that are more lenient about this.

And about the long work hours, I'm doing it right now because I am young, and if compound interest works out, it will give me a lot of financial security to do things starting a company. That is, if this thing doesn't backfire.

hashxyz··on Ask HN: I want to start a company, but I am currently overemployed
This was oddly reassuring. I am aware that I don't know the first thing about software sales for example (except that it is a job I would probably want to hire people for down the line). I am keeping my eyes open for a way into the market, but it's a big problem since all the competition is decades old and has so many critical features.

> Don't draw attention to yourself

That's what I've been doing up to this point. Unfortunately I am naturally starting to build a name for myself as I become the only person with much knowledge on the projects I work on. Trying to start a company would obviously mean ramping that up even more.

hashxyz··on Ask HN: I want to start a company, but I am currently overemployed
As stated already, there would be no time, but maybe they would bankrupt me.
hashxyz··on Ask HN: I want to start a company, but I am currently overemployed
There are multiple FAANG companies involved, so I am sure they would make an example of me if they had a chance. I think the push for RTO is due in some small part to the fact that my situation is almost impossible for companies to prevent right now.

That last suggestion actually seems like a good idea that I hadn't thought of. I think I would fit a lot better as a CTO than a CEO, so I will see if I can aim in that direction.
