Seems like a forced analogy. Is the signal a periodic and regular frequency?

If its a straight line you need 2 samples.

If its not you probably need more.

Id argue codebase understanding is neither of these simplifications

And the sampling theorem only applies when you only know that the signal is band-limited. If you know more than that, you can go below the Nyquist rate.

I love aliasing in digital synths -- embrace the foldover.
