I'm extremely cynical about the way the US government would react to any sort of financial crisis. I do not believe that they would not completely cave and bail out the AI companies and the monopolists if there is a downturn. And it's not that I don't trust the Republicans specifically. The whole political sphere is completely convinced that AI is a national security prerogative, and the cynical political atmosphere will equate national security with investor protection.

Let me append the saying a bit: The US government can remain irrational longer than you can stay solvent.
