1. since AI has captured the imagination of capitalists and they think this is the next industrial revolution, they gotta be in it to win it. combined with the fact that i believe most people here are wealthy or at least aspirationally so, that explained half of it.
2. the other half is that AI as a tech is interesting from a mathematical and compsci point of view, tho certainly not interesting enough to justify the proportion of topics about it here.
i guess i should add a 3rd reason.
3. ycomb has a financial stake in spreading the news about how wonderful this tech is!
lolol
