Naw, the you up there was meant as a passive for all those who believe in
hard take-off due to hardware capacity going to near infinity in a short
period of time.

Yep, though many NP-hard problems do have good polynomial approximation
algorithms (and then some don't and never will unless P=NP).

My own belief on the matter is also that P != NP, but we must consider all
possibilities in order to understand the choices.
