Until they are built, it's all talk.

They are built, at least one in Phoenix:

> As of 2025, the first fab has been completed and is producing four-nanometer (nm) chips.

One is built, OP said 10.

Gotta start somewhere. Plus foxconn only abandoned 1 DC build out during Covid, a bit different from TSMC investing billions to build multiple, of which they already built 1.

TSMC also AFAIK is forbidden from setting up bleeding-edge fabs outside of Taiwan?

Four more 2nm (or below) fabs in Arizona. That's bleeding-edge or very close to it.

By end of decade, no? Seems like domestic fab will always be two steps behind. I assume by design.

They're building 1.4nm in Taiwan

Will they remain bleeding edge by the time they are operational?

Intel latest is the bleeding edge and more advanced than TSMCs.
