You can get exactly the same kind of feeling with RF too, I worked around that space for a decade or so and the structures and effects that felt magical I look at and just see capacitance, inductance, coupling, loss etc. - still interesting, but it hasn't felt like magic for years anymore.

It is kind of hard to explain but the first time I learned about digital/analog conversion and wired up a very simple speaker and made it play any note I wanted by simply tweaking the processor’s clock, the magic left me. Before then I couldn’t even fathom how that worked, then it was like “that’s it?”

Just an overwhelming sense of disappointment in how much sense it made that it worked that way and not a myriad of more spectacular ways I’d imagined when I was a kid taking apart ancient IBM color monitors for fun

Biochemistry is pretty magical, have you tried digging into that? Immunology or protein folding might be just the thing for you.
