I gave you multiple sources. If you don't want to look them up that's on you. Not that I'd recommend it, it makes for pretty dry reading and doesn't really have anything to do with your misconceptions about the industry.
You don't really seem to grasp the sheer scale of it, how complex all the subsystems necessary to get a process running are, and how open exchange can be on these subsystems without giving away any valuable secrets. Or that none of what I was saying was downplaying where the Chinese stand. I listed most of the companies necessary to get the modern western nodes running and pointed out that trying to achieve autarcy for all of that is a herculean task. The Chinese now only being ~two generations behind with EUV and compatible photoresists as the last hurdle to catch up has been break neck pace. They're likely to achieve parity in a couple of years. And when that happens we'll know it, just like we know about how their 5 nm process works.
