As long as Chinese companies keep pushing on, so must US companies too.
It would not surprise me at all if we suddenly start seeing top US AI companies lobby against Chinese models, or even the gov. making it illegal to use Chinese AI models.
But in this day and age, I just don't think it is possible. A distant third option would be that the big AI companies try to make hardware so expensive that people simply can't run their own models, while blocking access to foreign models.
