> For ex: imagine a Chinese AI engineer working at OpenAI develops a new tool that generates enough $$ to support a whole team.

Whose to say an American, given the same opportunities, couldn't do this as well? If you look at where the top AI companies are, only 1 is in China.

I don't think h1b mills impact tech workers as much. Most of those cases seem to be in the healthcare space or in low end tech jobs that Americans probably don't want anyways...
