Look at the semiconductor companies and how all the fabless players dwarf Intel. TSMC is just crushing Intel which cannot even field new products without massive government and external capital flows.
Giants like Apple, Microsoft and Google are bigger than the entire semiconductor space, so of course it’s in their capability and interests to build their own silicon.
There is no way any reasonable engineer would want to stick around Intel.
Intel’s disruption is now complete and is not an economically viable entity with the current business model.
