if anything we are producing too much food and what communications you find lacking?

the main bottleneck for the civilization in communications currently is the sparsity of cynical, negative HN comments

nerds favorite pastime is to go “um actually ”

Food distribution is still a problem in vast part of the world. Handling food waste is another issue. Climate related shortage are coming soon for us (at the moment they only manifest as punctual price hikes - mustard a few years ago, coffee and chocolate more recently, etc... https://www.euronews.com/green/2025/02/13/goodbye-gouda-and-... https://www.fao.org/newsroom/detail/adverse-climatic-conditi... https://www.fo…

It feels like you didn’t read your own link as he somewhat addressed your concern directly. The idea is simply that AI investment is an “up front cost” to future improvements. To debate against it you would have to provably explain why you think AI will not advance other technologies whatsoever.

it is difficult to comprehend for me that soneone spends all this time thinking through and calculating how to harness as much energy as possible and then wants to use it for large language models instead of something useful, like food production, communication, transport or any other way of satisfying actual human material needs. what weird priorities.

Well, I've never seen anything written by AI evangelists that doesn't sound like it was written in day three of an adderall binge. This essay is no different.

From a purely engineering perspective I think it becomes difficult to argue with the gas turbine once you get into the gigawatt class of data center. The amount of land required for this much solar is not to be understated. In many practical scenarios the solar array would need to be located a distance away from the actual data center. This implies transmission infrastructure which is often the hardest part of any el…

Sadly, I agree until we get SMRs (I think we are few years off). Obviously it would be more ideal to use grid+solar with curtailment but not super realistic.

LLMs and other IT applications have the distinct advantage that they require no other raw materials as input, aside from initial setup, extension, and maintenance. Under these conditions the requirements essentially boil down to real estate and high bandwidth internet connections. Also, demand for AI is currently so high that the solution can be scaled up far enough to be viable.

All the other concerns require more subtle approaches because human requirements are much more messy.

Whether you like it or not, we are burning a lot of electricity on datacenters. That is a fact. And energy consumption is likely going to significantly increase in the near future. If we can reduce that energy usage, that is a good thing and a big improvement.

I do not think I even understand your complaint. Different people can work on different problems. We do not have to pick only one.

> My improvement is more important than yours.

We can just do both.

Slightly OT, but I see the Chinese are talking about space DCs now too which would suggest they reckon it could work too. (Unlike me and others here)

Except none of that data center grade chips can work in the space. No GPUs, no memory, no SSD. They are not radiation-hardened (rad-hard). Rad-hard chips generally cost an oder of magnitude or more compared to normal commercial chips, and they are in general an order of magnitude less complex, plus they operate much lower frequencies. Data centers in space is straight up stupid.

We don’t do both. We spend trillions on AI.

I am hoping nuclear batteries make a comeback by the desire for all this compute and its voracious appetite for energy.

We have rolls royce small modular reactors (SMRs) driving a similar functionality in the UK

For context, at the moment they hope to have them operating some time in the 2030s. That’s a best case, just like the cost estimates (which operating practically and safely may be more than what people are forecasting)

Not operating today like it sounds from the comment.
