That's because commodity stuff has become more complex. You can still
understand stuff from 20 years ago as easily as you could 20 years ago
(assuming you knew enough then, obviously).
Two more decades in that direction, and who'll
know
*what* is "under the hood"?
The engineers building X usually know how X works. There's
probably no one person at my place of work who knows
*everything* about all of the hardware and software, but there's
always *someone* who knows whatever it is I happen to need
to know. Admittedly the PSUs and batteries are bought in
(as are the chips :-)) but if we really needed to know more
than the datasheets tell us, we could find out.
