It will take decades for the US to get where Taiwan is now in semiconductor manufacturing, if ever. It's not just about building the most advanced chip factory. It's about re-aligning the entire nation's value system and culture to allow such development to happen in the first place.
We complain about the money we spend already. And now we're supposed to subsidize an entire industry to the point where we can build the most complex machines known to civilization at scale in a time-frame that matters to a global conflict that's potentially approaching soon? I don't see it.
It's taken about 8 years to realign the US from a democracy to a fascist regime, something that was nearly unthinkable. This isn't a hard problem with the right propaganda and manipulation.
TSMC aims to have N3 in Arizona by 2028 at the earliest which is 6 years after it first released. By that time, TSMC will have released N3X, N2, N2P, N2X, A16, and A14.
TSMC is heavily sponsored by the Taiwanese government and was created with the express purpose of making Taiwan so valuable that the West would be forced to defend them against China. Moving newer processes out of the country is against their national interests and they've made it clear that there's no plan to do that.
Would it though? The TSMC foundries are pretty much in every continent. Are they just going to stop operating if this happens? Because that seems akin to killing a golden goose.
Also what is up with Global Foundries? I don’t hear a peep about them.
