> Many commenters on HN have this weird idea that if Taiwan is slightly ahead of competition, US would defend Taiwan against a country with nukes. Or that TSMC superiority is Taiwan's national security issue.

Well... TSMC is definitely a component of Taiwan's national security. It's called the "Silicon Shield" for a reason.

And the US definitely has more reasons to go to war, and more importantly, threaten war to prevent one breaking out, over Taiwan if it knows there will be a massive economic impact.

And China definitely knows that if Taiwan is important for the US, it's almost certain the US would defend it.
