What kind of logic is that? It reminds me some people I know that vote to extreme-right parties because "well, we know that the regular parties are not gonna change anything. These new guys may do something new. Who knows, let's vote them and find out"
Well, no, I think that the claim is that having nuclear power plants is better than not having them. If they're not sucking energy off the grid (like what is happening right now), that at least will help avoid regular people like us having to pay the increased prices and indirectly subsidizing them.
And nuclear energy is clean (from a climate change perspective at least), and so if they're going to keep spending huge amounts of energy AI training anyway, it's probably better to do that in a way that isn't going to keep boiling the planet.
Also, if there is any kind of excess energy then it can be fed back into the grid, meaning that grid power can be fed from something relatively clean compared to something dirty (like coal).
I'm not entirely sure how this relates to the party thing. I'm saying that sometimes something selfish in a capitalistic system can occasionally still be a net good. I didn't think that was controversial. I'm not saying we give Zuckerberg a trophy or anything.
