Not sure why the government would bother to bail them out. I would imagine Google could take up most of the slack if OpenAI implodes.
With AI? Well just sell the assets in bankruptcy. Models can be sold, hardware and infra can be sold, IP and brands too can be sold. Employees, they have mostly transferable skills and are mobile already.
Even if AI companies fall, other people can pick up the pieces if there is something valuable left. Market might be affected. But I don't think it is only domino.
Entire stock market will tank and a lot of very rich people will lose a lot of money. So government won't let that happen.
So bailing out might actually cause the stock to appreciate because uncertainty about the possibility of bailout suddenly disappears in a positive manner.
Otherwise said, high level corruption that is not even hidden these days.
