See below - whether they have it themselves or not, they can bully to have it:
I've already accounted for that. I already think of the entire West as part of the American Empire. I'm saying to you that even if we assume the US had a certain stake in controlling vassal technologies too, they still don't match China now when we look at the completeness of the technological stack.
I've met with hundreds of Chinese leading companies in each of these fields so when I tell you I know, I really know.
Then you possibly don't consider some truly high-tech areas as high-tech just because the West has no monopoly over them and China has a traditional lead in them.
As much as we shit on Gordon Chang for calling China's collapse, it is equally as dumb to call for the collapse of the US for 10 years in a row and have it continue to plod along.
That's a false equivalence fallacy, I'm sorry, but if you are a sincere and rational person, then it is impossible to equate Chinese doomers with US doomers in any way.
