I disagree. We do need fabs because we need the expertise.
As we do have fabs and do have the expertise. Intel produces all of their most advanced chips in the USA. The chips are competitively priced and made with US wages so...
Until "recently" (mobile phone era) Intel/AMD basically had no competition. They completely missed the mobile market and are now seeing competition from ARM in laptop/server. An there is also RISC-V on the radar. When/if CPU architecture becomes more de-monopolized, manufacturing competitiveness will be a big factor.
