As regards the lesser availability of American tech, I'm sure that's much more limited in China, which coincidentally happens to have the most notable domestic AI industry outside of the US. It's something that economists can be reluctant to admit, but for which there's solid evidence by now afaik, that at least temporary import barriers, if done right, can be a boost to industrial development. The thing that is weird about the EU regulation is that they're putting the same shackles on their domestic tech industry, which is dwarfed by the giant US incumbents who have more resources to invest in compliance than startups (apart from the bits that apparently only target said encumbants that some posters have mentioned here, which I don't know anything about).
