There's this preoccupation I have since the advent of going "digital", let's say since I
heard music being played on CD in the early 80s. I grew up with access to electronics
equipment that would generate "square waves" in some sorts of analogue fashion, including
originally "digital" chips,
Comments in line.

My tl;dr answer to your question is it's difficult because even if it's
digital, it's not digital. Ever. It's always analog.
Like you, I'm a university EE (and Comp. Sci.) because I wanted to go into
chip design. This was back in the early 80's. So maybe my classwork was
different than

I think I disagree with this definition of a square wave. This is what a
perfect, ideal one would look like, but even in reality I don't think any
system (digital or analog) can exactly

75th or 150th harmonics?
A bandlimited squarewave of 8 kHz @ 44.1 kHz samplerate is a sinewave. 3 *
8 kHz is already outside of the bandwidth.
This means that the basic frequency must be pretty low to get a square wave
shape.

Well the example used was Middle C, which is 261.6 Hz. And would have 75 or
so harmonics before reaching the limit.
