AFAIK the cost of producing semiconductors on a leading-edge node are so high you are forced to aggegate demand across seveal chip designers. Intel offering foundry services is evidence of this dynamic.
Edit: grammar.
True, but aside the internal demand I don't see why can't they get external customers.
I think Samsung did the same.
Economics, I'm guessing. They got enough money floating around recently that they would've done it by now, if it made em more money.
Their pockets are flush from crypto and now AI.
I assume they don't want to loose focus on software, which is currently their moat.
