Costs come down at scale. Vote with your wallet, tell your friends, and we just might have our faster+better+cheaper problem solved.
This is HN. Asking people here to consider any long-term geopolitical ramifications associated with their economic activity is futile.
I don't see why non-US companies should "vote with their wallet" by over-spending so that they can have a US supply chain instead of a Chinese supply chain. They're both foreign, outside their control and vulnerable to political stunts.
