The PRC will happily sell chips to the West. I live in Taiwan, I don't want it to happen, but people need to stop acting like countries will prevent an invasion because it means the CPC will control chip manufacturing.
The choice is between possible nuclear war, or, the 5090s are more expensive and sometimes Americans can't buy them when the PRC is punishing the west for something.
Honestly, this is the most reasonable comment here, especially coming from someone in Taiwan. I hear similar views when I'm in Asia, which are very different from what I hear back in the West.
