Regarding AI safety, of course.
The detailed version of this question follows: "Is AI safety sufficiently talent-constrained, and on an imminent enough timeline,
that me and any friends I can convince ordinary non-Ivy-League non-top-tier computer scientists, mathematicians, and programmers (including students)
should drop everything (including things you are personally uncomfortable telling people to drop out of)
and apply for every grant out there?"
I would also accept "If you are not very talented, go do something else and let us handle it", or "If you're unsure of your talent, here is a link to an online test or open application thing that will give you good evidence one way or the other".
I do think it is crunch time probably, but I agree with what Rohin said here about what you should do for now (and about my minority status). Skilling up (not just in technical specialist stuff, also in your understanding of the problem we face, the literature, etc.) is what you should be doing. For what I think should be done by the community as a whole, see this comment.
