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)
