The last great economic expansion or at least economic reconfiguration was internet services (which of course is mostly distinct from financial services) and the US ended up with a very dominant trade position in internet services.
The internet infrastructure is great. Networking hardware is great. Private internet companies built on top of it? Big whoop
I was not commenting on whether the world would be better off if the US were less economically dominant.
There’s very few internet companies doing truly unique, irreplaceable work.
