Yeah, and I should mention that the idea to make the foundry a big part of Intel's business came from a past CEO who was an MBA (circa 2010-2011), and it was the engineers in the company who sabotaged that effort.

History showed the engineers to be wrong, and here we are with Intel trying to compete with TSMC for customers.

That TSMC has a good business being a pure foundry doesn't mean Intel will have a good business being a mixed foundry.

I imagine a failed process step (10nm) would have been an even worse disaster if they had external customers for it.
