I'm deeply uncomfortable with:

1. US government having substantial voting shares in any AI company.

2. USG investing in or extracting shares from specific AI companies and not others.

I understand the case for having a bulwark against hypothetical future AI job loss.

At the same time the greatest AI risk is concentration of power. Few things would accelerate that more than the USG being able to (and having the incentive to) kingmake specific AI companies.

If you think this is a good idea, imagine all the ways it could be used by an administration you deeply distrust or that you view as having totalitarian leanings, whatever your political beliefs are.

The AI landscape ought to be one of democratization of AI, diversity of options for customers, and checks and balances within the private sector, and between private companies, users, and government. Not one where government co-opts these companies, directly or indirectly.
