From chips production process, we can see clearly that both US and CN are not the world’s economic superpower any more.
Dutch company ASML manufactures the advanced lithography machines, US only design the chips, then chips are manufactured in Taiwan or South Korea, tested and assembled in Southeast Asia (Malaysia,VN), and then built into products in China.
SO, US only do the design, thats not so important thing. CN can't make lithography machines and also can't buy lithography machines for 5mn chips due to sanction, so CN only can build the chips into products and thats not so important, too.
So, No more the world’s economic superpower. If CN or US collapse, then another countries will take the chips design and built into products jobs. No one care if US or CN collapse, at least in chips industry.
