China knew that chips were security and strategic issues maybe 20 years ago if not more, I wonder why they haven't done building equally capable factories on-shore.
Because cutting edge chips are not. They are nice to have and sell for a lot. But for vast majority of things you can absolutely manage with chips they can produce. And in some cases those top end chip technologies are not even useful for those purposes.
We are so deep in AI and super computing or wasteful server side computing that we forget that lower end chips are in absolutely everything. And China can produce those just fine.
