The shame of all this is that now every country will have a worse, more expensive - but yes, soveriegn - solution, and the US makes less money through trade. Everyone loses, except people who want to hurt western economies.

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.

Or maybe a better product that’s cheaper. Let’s not let hubris get the best of us. There’s nothing special about the US. I mean imagine being an Oracle customer and switching to a local supplier. Must be like emerging from a nightmare
