Once AI development is completely automated in top ai companies, what reason would the govt in usa or china possibly have to not take over the company and it's assets?

Explain Like I'm Normal

The discussion revolves around the inevitable point where AI automates its own R&D, potentially rendering the 'innovation' incentive of the free market obsolete. If a private entity controls a self-improving superintelligence, national security and sovereign interests would likely force a government takeover of the infrastructure. This shifts the focus from building the best tech to surviving a geopolitical asset seizure.
