Not in his field. If you have knowledge in a critical field, you'll get the funding in China. If the company didn't have it, then the government will. I don't care if he got angry; he couldn't handle it and went crazy, so he's gone. Not everybody has to be nice to each other here, especially if you that something's fishy about a story, but you do have to control yourself. No matter what anybody says to you, you can report it to a mod if you think he broke the rules, eat it because you can't rebut it, or rebut it intelligently. If you start throwing profanities, then you're out. Simple as that.
So basically you're asking me, if every single thing goes wrong for China, what's the bottom line, right? And for some reason, I should entertain this as if I have all the privileged information in China. The best answer is to just watch and see because so many things are going on that we don't know about and China is nothing but depth in terms of talent. But the more entertaining answer is that if everything goes wrong, it all rests on SMEE. Whenever SMEE can get modern lithography to work well, SMIC will be online making the best chips possible with them. The better SMEE is, the better SMIC and Huawei are. TSMC isn't even all that important because it's not independent in its tech. When China figures out the whole chain from lithography its application, that's when China will enter its final unstoppable ascent. It cannot happen before that.
It's simply not intelligent to go further and ask what if all the research efforts fail again and again, wouldn't you agree? If China can't innovate, then China will fail. That is an imminent fate for all countries that cannot innovate.
