There is no organization called "antifa" - so, why label a non-existent group "terrorists"?
This gives the regime maximum scope to hunt down opposition and critics. They label you "antifa", and then they come for you.

This is why it riles me up when people accuse environmentally-focused criticism of AI of being hollow or without evidence, when every single one of these Very Serious men can just say whatever they like, and still get treated as being 'experts'

So energy …
Fusion’s gonna work.
Fusion is going to work. Um. On what time frame?
Soon. Well, soon there will be a demonstration of net-gain fusion. You then have to build a system that doesn’t break. You have to scale it up. You have to figure out how to build a factory—build a lot of them—and you have to get regulatory approval. And that will take, you know, years altogether? But I would expect [Helion 20] will show you that fusion works soon.
20 Helion, a clean energy startup backed by Altman, Dustin Moskovitz and Reid Hoffman, focuses on developing nuclear fusion.
In the short term, is there any way to sustain AI’s growth without going backward on climate goals?
Yes, but none that is as good, in my opinion, as quickly permitting fusion reactors. I think our particular kind of fusion is such a beautiful approach that we should just race toward that and be done.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:66lbtw2porscqpmair6mir37/bafkreiee7jjkbneuad2nrf4n2muxyl4ud6st5pnnr37b6tqep2nhnyreby@jpeg)
