From what I've heard they aren't offering competitive salaries, so introducing people at insane comps would probably destroy existing teams(if there was no salary bumps to match)/budgets (if there was). Doubt you can do much with new hires in 1 year in such environment, by the time you start seeing results it's probably too late to capitalize on this bubble.

More likely, they wait to see how the AI HW startups shake up and then acquire the ones that have anything worth paying for.
