You would be surprised.
There are two sorts of 'universities' -  those that are essentially 
vocational and teach you *what* to think, what  you  need to get a job, 
and those that are theoretical that teach you *how* to think (like e.g. 
and engineer).

There are very very few people in the business of designing processor 
architectures. You learn that on the job.

None of the things I ended up doing were explicitly taught anywhere 
academic but at least my university did teach me *how* to think, and how 
to go to first principles to tackle a previously unknown problem.

In every field there are people - a very few people - who actually know 
a narrow  speciality inside out. A university friend was involved in 
NAND flash development for example.

Another friend was instrumental in building the first compilers for ARM.

I worked on cutting edge avionics for a while, and then switched to 
audio electronics.

Very few other people in that field at the time

The point is that you don't need very many very bright people to 
generate businesses that employ and are run by  millions of much more 
stupid people.

CPU design goes back to Turing and Von Neumann. Just two people really.
