Wow. AI has already accomplished more positive in a few years of big commercial stuff (admittedly as a side effect) than cryptocurrency has since, say 2009. :(
Crypto created a trillion dollars out of thin air (well, slightly thicker air from more CO2). AI is poised to do the same, but also has already polluted the entire internet with worthless slop.
If using a ton of energy has to happen then I'd prefer it be generated from nuclear, but I don't see the need to supply LLM data centers with a ton of energy as a positive.
Solving the political problems behind nuclear power (getting TMI restarted being one of the more difficult politically but easier technically), and generally bringing the "build more nuclear" to forefront.
(Although to be fair there's been a fair bit of wind and solar subsidized heavily by crypto, as well as flare gas power generation, and a bit of PV solar)
