I wouldn't know how to even begin to measure the probability for something like that, and I doubt if you do either.

Then what's the point of mentioning it?

The three exception were number 37, 42 and 383 on the list which had Japanese microprocessors. Nobody used Chinese processors including the Chinese.

Memory chips are commodities, microprocessors are not. It's also interesting that the operating system for almost all the supercomputers on the list is Linux, and China didn't develop that either. When IBM made their first PC almost 30 years ago it made a very big splash, they thought they owned the home computer market and for a short time they did; but IBM didn't control the microprocessor or the operating system. Today IBM no longer makes PC computers.

I imagine China would rather like to control a vital and very profitable multi billion dollar industry that has profound military implications, but they don't.

That's the thing, starting a microprocessor industry from scratch would be a very large bother indeed.
