So, what, should I withdraw my 401k and buy physical gold?

That's up to you, but if there is a crash it's very unlikely to be before a major hyperscaler decides to reduce or stop their infra expenditures (which isn't happening, like, quite the opposite). That's what I would personally see as the top signal, but it's pretty dumb to exit the whole market because of a possible crash at some point in the future, without anything you see as a catalyst. Also, gold is completely overrated, it's not at all a safe place where to put your money and you have no idea how it would correlate with an AI bubble burst

		Fiat money sure came in handy when 10% or more of the trees in my entire county were blow over toward the east. Long term, you're getting eaten by inflation, but when the power grid, and most cell sites are down, cash is still king. The real lesson I've learned is that a small generator consumes about 10 gallons of gasoline per day. There's no way to store enough of it to last through a total collapse, even if you could keep it from being stolen.
