So, how do faders and knobs work nowadays?

Oh, are they perhaps still potentiometers, with the difference that you can now low-pass filter them before reading off and digitising their values, since you don't have to pass the audio signal through them?

Some knobs use rotary encoders. A nice side-effect is that they are "infinite" in either direction, unlike helical or single-turn pots.
