Are these incentivized humans as organized, well-funded, or smart as the people working at the frontier labs?

If my "millions" is an underestimate, why haven't other labs using their own unique training methods/data/etc stumbled into RSI? Sorry if I'm misunderstanding; I'm struggling to understand what you wrote.

I'm pretty sure we agree on humans being stupid, but that doesn't mean that suddenly we get human extinction. You gotta connect the dots for me here.

Not OP.

Why would it be millions in 50 years?

The think about nuclear weapons. In the early days, it was limited to the super powers. Now 9 countries have them and a country like Iran is capable of acquiring them.

Is destructive AI be any different?

Genuine question.
