These are not topics you will just figure out on your own or "on the job".
The other aspect is the professional engineering credentials. At least in Canada Engineering is a protected title. of which the easiest way to get your P.Eng is getting a degree through an accredited engineering program.
There is a reason why so many people from engineering can switch to software while the converse almost never occurs.
Yes. I think American society will struggle to produce enough competent electrical engineers outside of the university system.
> there's going to be some big reorganization to reflect the fact that you can now learn just as well OUTSIDE of a university context
In my experience, very few people like learning the math needed to be competent at RF. It’s hard and exhausting and without a human connection most people are going to bounce. This isn’t like software where if you get it 80% right something still occurs.
I’ve worked with homeschoolers too, and unless they’re the small fraction of people for whom math comes naturally, they’re not going to study it on their own. But that’s exactly the audience one has to reach to grow the EE supply.
