FWIW, There are all kinds of computer weenies running loose... they are a dime a dozen.

They know software and can swap boards(maybe), but the true shortage in in the folks that actually design, and manufacture the parts, and machinery to make the parts, then be able to maintain and repair the stuff.

There will always be a need for engineers to design, build, install, and repair stuff.
That is an art in itself.

Its not rocket science, its more complicated than that.
