I get the impression that the semiconductor industry is slowly disappearing from the US, and even from the West as a whole. It'll be a lot harder to regain that expertise than it is to lose it.
The arrogance of Intel when they overlooked the mobile “computer” (aka iPhone and then others) accounts for the largest strategic mistake (and rational by bean counters):
TL/DR (or you can't get pass the paywall) - Intel is in talks with SK Hynix to sell the non-volatile memory solutions group (NSG) to SK Hynix for ~$10B. It's not clear if this is just the NAND business or if it includes Optane technology as well. If there's any official confirmation of this, it'll come after the markets close at 4pm Eastern time...
