That sort of crash is what central banks exist to protect against. That could be something like the Fed stepping in as a buyer of last resort and picking up several trillion dollars of equity, and/or pushing rates to zero again to incentivize private capital to more or less do the same.
A global crash of financial systems is unlikely because it’s cause too much pain for everyone. It unfortunately means we plebs are likely the ones paying to bail it out.
Frankly, I would be happy if riots in the streets happen (if there is a bailout of Big Tech in the first place). What's going on recently with OpenAI publicly, and probably most of the 'AI' players not publicly, is disgusting - it's a bubble, everyone and their mother knows it, and these guys try to save their asses by asking for governement backing before the bubble even pops. Privatize gains, socialize losses...
It's a shame that no more bankers went to jail after 2008, although I find the situation was much more complicated than here.
Oh, don't get me wrong, if and when this happens, I'll join the riots.
And I'm not even anti-AI; I genuinely believe that, as a technology, it is a major advancement that can and should be put to so many good uses. Which is emphatically not what the people in charge are doing.
Its so big that it could take with it whole global market.
There is no safe asset you can turn into in such a case, digital money would literally mean nothing when whole financial system collapses.
