Tiresome take that's been repeated time and time again. China has problems like any other country larger than Luxemburg. But the conclusion that "china is fucked" sounds more like a wish than anything else to my ears. The Chinese economy is growing ~5% per year. It's got one of the worlds most well educated workforces. It's manufacturing everything from basics to high tech and very little indicates that's about to change anytime soon.
The chip technology sanctions might slow development in that area in China, but I wouldn't count on it.
