> The US has invested trillions in AI that the companies involved are never going to make back. Even without competition from open models, but definitely not with it. And if those trillions turn out to be worthless, that's going to have a massive impact on the market and cause a lot of bankruptcies.

This is the point. And what nobody seems to bring up that inference is a massively profitable margin. The labs can still grow at 80% margin as opposed to 99% margin (I do not have the numbers). But that will hurt the valuation and investors.

With protection from Govt, you can compete at 1.5 or 2x of the equivalent open weights price. But it is not sustainable to keep the prices high, just a matter of time.
