Relax. I’m sure they’ll be vetted and probably most won’t even be Chinese citizens. China is just as complicated a place as America^1. I’m an American software developer and I’d rather eat a bowl of hair than go work for my own government, much less any other. There’s lots of Chinese tech workers who just want to write software and not get involved.
^1 I’ll admit, Chinese food is more complicated. Like Louisiana vs Szechuan is a fair fight. I’ll take the Pepsi challenge with Memphis BBQ vs their best smoked pork. But after that, we’re gonna need to pretend Mexican and Italian food are American to be competitive.
That's a very strange title, I think in the end the US would suffer more, because China would be able to easily replace this talent, but the same cannot be said for the US.
I'm not understanding your idea. Why would it be harder for the US to replace tech talent? We're not restricted to just hiring US nationals. The green card queue is decades long. Ask any H1-B visa holder you know their 'priority date' for green card consideration. They'll be able to tell you immediately.
