PRC went from capturing $8 in final assembly fees on iphone3s to ~$100 / ~25% of BOM cost of iPhone X. More highend PRC components are making their way as well (hence YMTC about to get boot). PRC is also like 1/3 of semi market (400B), that's a lot of western semi R&D that industrial policy like 52B CHIPs act spread over multiple years isn't close to replacing.
