Tip for AI skeptics: skip the data center water usage argument. At this point I think it harms your credibility - numbers like "millions of liters of water annually" (from the linked article) sound scary when presented without context, but if you compare data centers to farmland or even golf courses they're minuscule. Other energy usage figures, air pollution, gas turbines, CO2 emissions etc are fine - but if you com…

Hey Simon, author here (and reader of your blog!). I used to share your view, but what changed my mind was reading Hao's book. I don't have it to hand, but if my memory serves, she writes about a community in Chile opposing Google building a data centre in their city. The city already suffers from drought, and the data centre, acccording to Google's own assessment, would abstract ~169 litres of water a second from lo…

I'm conflicted. Zooming out, the problem isn't with AI specifically but economic development in general. Everything has a side effect.

For decades we've been told we shouldn't develop urban centers because of how it development affects local communities, but really it just benefited another class of elites (anonymous foreign investors), and now housing prices are impoverishing younger generations and driving homelessness.

Obviously that's not a perfect comparison to AI, which isn't as necessary, but I think the anti-growth argument isn't a good one. Democracies need to keep growing or authoritarian states will take over who don't care so much about human rights. (Or, authoritarian governments will take over democracies.)

There needs to be a political movement that's both pro-growth and pro-humanity, that is capable of making hard or disruptive decisions that actually benefits the poor. Maybe that's a fantasy, but again, I think we should find ways to grow sustainably.

I will go meta into what you posted here: That people are classifying themselves as "AI skeptics". Many people are treating this in terms of tribal conflict and identity politics. On HN, we can do better! IMO the move is drop the politics, and discuss things on their technical merits. If we do talk about it as a debate, we can do it when with open minds, and intellectual honesty. I think much of this may be a reactio…

> On HN, we can do better! IMO the move is drop the politics, and discuss things on their technical merits.

Zero obligation to satisfy HN audience; tiny proportion of the populace. But for giggles...

Technical merits: there are none. Look at Karpathy's GPT on Github. Just some boring old statistics. These technologies are built on top of mathematical principles in textbooks printed 70-80 years ago.

The sharding and distribution of work across numerous machines is also a well trodden technical field.

There is no net new discovery.

This is 100% a political ploy on the part of tech CEOs who take advantage of the innumerate/non-technical political class that holds power. That class is bought into the idea that massive leverage over resource markets is a win for them, and they won't be alive to pay the price of the environmental destruction.

It's not "energy and water" concerns, it's survival of the species concerns obfuscated by socio-political obligations to keep calm carry on and debate endlessly, as vain circumlocution is the hallmark of the elders whose education was modeled on people being VHS cassettes of spoken tradition, industrial and political roles.

IMO there is little technical merit to most software. Maps, communication. That's all that's really needed. ZIRP era insanity juiced the field and created a bunch of self-aggrandizing coder bros whose technical achievements are copy-paste old ideas into new syntax and semantics, to obfuscate their origins, to get funded, sell books, book speaking engagements. There is no removing any of this from politics as political machinations gave rise to the dumbest era of human engineering effort ever.

The only AI that has merit is robotics. Taking manual labor of people that are otherwise exploited by bougie first worlders in their office jobs. People who have, again with the help of politicians, externalized their biologies real needs on the bodies of poorer illiterates they don't have to see as the first-world successfully subjugated them and moved operations out of our own backyard.

Source: was in the room 30 years ago, providing feedback to leadership how to wind down local manufacturing and move it all over to China. Powerful political forces did not like the idea of Americans having the skills and knowledge to build computers. It ran afoul of their goals to subjugate and manipulate through financial engineering.

Americans have been intentionally screwed out of learning hands on skills with which they would have political leverage over the status quo.

There is no removing politics from this. The situation we are in now was 100% crafted by politics.

And also, none of those current use cases are a real benefit to society, outside of maybe research cases. The only benefit is to the already wealthy owner class that is itching to not have to pay for employees anymore because it impacts their bottom line (payroll is typically the largest expense). It's not like we are making robots to automate agriculture and manufacturing to move toward a post scarcity, moneyless so…

You appear to be arguing against using technology to boost human efficiency on a forum full of software engineers who've dedicated their careers to building software that makes humans more efficient. If we aren't doing that then why are we building software?

Does the future productivity growth that would have been gained later (due to more junior engineers not entering the field) outweigh the AI gains?

If it's just the little productivity boost now, I think it's a net negative if hiring trends continue.

I think it's a discussion to be had but talent pool is a tragedy of the commons situation.

Water location matters. Is the data center in a desert with scarce potable water for locals? Or is next to a large Canadian lake, plenty of potable water, with people who want to trade something for currency so they can put avocados in their salad?

Farmland, AI data centers, and golf courses do not provide the same utility for water used. You are not making an argument against the water usage problem, you are only dismissing it.

They are making an anti-disruption argument.

I think it's bad though to be against growth, for reasons I've described in another comment.

> Briefly, the argument goes that if there is a 0.001% chance of AGI delivering an extremely large amount of value, and 99.999% chance of much less or zero value, then the EV is still extremely large because (0.001% * very_large_value) + (99.999% * small_value) = very_large_value I haven't heard of that being the argument.

> I haven't heard of that being the argument. The main perspective I'm aware of is that more powerful AI models have a compounding multiplier on productivity, and this trend seems likely to continue at least in the near future considering how much better coding models are at boosting productivity now compared to last year.

This is the new line now that LLMs are being commoditized, but in the post-Slate Star Codex AI/Tech Accelerationist era of like '20-'23 the Pascal's wager argument was very much a thing. In my experience it's kind of the "true believer" argument, whereas the ROI/productivity thing is the "I'm in it for the bag" argument.

Can you? You have weather readouts. One set is from a weather simulation - a simulated planet with simulated climate. Another is real recordings from the same place at the same planet, taken by real weather monitoring probes. They have the same starting point, but diverge over time. Which one is real though? Would you be able tell?

They're not asking about telling the difference in collected data sets, data sets aren't weather. The question is can you tell the difference between the rain you see outside your window, and some representation of a simulated environment where the computer says "It's raining here in this simulated environment". The implied answer is of course, one is water falling from the sky and one is a machine.

You experience everything through digital signals. I dont see why those same signals cant be simulated. You are only experiencing the signal your skin sends to tell you there is rain, you dont actually need skin to experience that signal.

Earlier quoted context omitted.

it is an architecture problem, too. LLMs simply aren't capable of AGI

Why not? A lot of people say that, but no one, not a single person has ever pointed out a fundamental limitation that would prevent an LLM from going all the way. If LLMs have limits, we are yet to find them.

We have already found limitations of the current LLM paradigm, even if we don't have a theorem saying transformers can never be AGI. Scaling laws show that performance keeps improving with more params, data + compute but only following a smooth power law with sharply diminishing returns. Each extra order of magnitude of compute buys a smaller gain than the last, and recent work suggests we're running into economic and physical constraints on continuing this trend indefinitely.

OOD is still unsolved problem, they basically struggle under domain shifts and long tail cases or when you try systematically new combinations of concepts (especially on reasoning heavy tasks). This is now a well documented limitation of LLMs/multimodal LLMs.

Work on COT faithfulness shows that the step by step reasoning they print doesn't match their actual internal computation, they frequently generate plausible but misleading explanations of their own answers (lookup anthropic paper). That means they lack self knowledge about how/why they got a result. I doubt you can get AGI without that.

None of this proves that no LLM based architecture could ever reach AGI. But it directly contradicts the idea that we haven't found any limits. We've already found multiple major limitations of the current LLMs, and there's no evidence that blindly scaling this recipe is enough to cross from very capable assistant to AGI.

If it was evaporative, the amounts would be much less.

Imnot sure why you're saying it would be less? All sources I can find say that evaporative cooling is a tradeoff of more water for less power.

Just from a physics standpoint.

If you discharge water into a river, there are environmental limits to the outlet temperature (this is a good thing btw). The water can't be very hot. That means you need to pump a large volume of water through because you can only put a small amount of energy into each kg of water.

If you evaporate the water on the other hand, not only is there no temperature limit but it also absorbs the latent heat of vaporisation. The downside is it's a lot more complex and also the water is truly consumed rather than just warming it up.

This is the real AI risk we should be worried about IMO, at least short term. Information technology has made things vastly more complicated. AI will make it even more incomprehensible. Tax code, engineering, car design, whatever.

It's already happening at my work. I work at big tech and we already have a vast array of overly complicated tools/technical debt no one wants to clean up. There's several initiatives to use AI to prompt an agent, which in turn will find the right tool to use and run the commands.

It's not inconceivable that 10 or 20 years down the road no human will bother trying to understand what's actually going on. Our brains will become weaker and the logic will become vastly more complicated.
