Apple likes to own the core components of the stuff they sell. How surprising would it be for Apple to buy Intel's factories and hire away some of TSMC's top scientists and engineers?

Apple doesn't buy its manufacturing partners.

If you can make something with the quality Apple wants, they will buy you a manufacturing line in exchange for price, quality and production level guarantees.

Since Intel needs large customers for its Fab and capital investments, it would be a good deal for them even if the profit margin is much lower than they would prefer.

Apple really doesn't like to own manufacturing. They want to be in a position of a favored key customer, but still have the ability to switch vendors at a moment's notice if they can get a better deal.

Very surprising. It would be an unprecedented amount of responsibility for Apple to subsume when they could let the fed nationalize it and save a few billion dollars for a rainy day.
