FWIW, it's digital electronics

What other kinds of "electronics" are there?

Analog electronics [0] uses a continuously variable signal while digital electronics interprets the signal with thresholds that define states like 0 and 1.

Here is a simple example: using a few discrete parts, like two transistors (Darlington pair), a LED and resistor, you can create a simple circuit that shows varying brightness of the LED depending on how close you move your hand or an object to an antenna connected to one of the transistors (forming a sort of proximity sensor). No microcontroller, SBC or even a hint of a digital signal involved at all.

Probably the wrong way to look at it. Digital electronics doesn't really exist outside of theoretical spaces. It's all analogue underneath and any experienced digital designer will know that and what the consequences for things like signal integrity, noise immunity and latency.
