I think it's more likely we end up with a better software ecosystem. There will be plenty of companies for the foreseeable future willing to buy from either continent if one offering is substantially better. More competition will be better, as long as the US govt doesn't succeed in stifling it.

Microsoft for example has had a de facto monopoly in many areas for quite some time and I doubt many would argue that their software quality has flourished in recent years.

This is fair I guess. Assuming US tech got there by merit alone is probably a wrong assumption. Part of the "soft power" of getting to set the rules and whatnot.

If nothing else this gives me a positive outlook so thankyou :D
