Programmer Humor

I think it depends a lot on a person's individual knowledge. If you keep studying far enough away from your main area of expertise, there'll still be some point where you stop and have to blindly accept that something "just works", but it will no longer feel like that's what your main field is based upon.

Imagine a chef. You can be an OK chef just by memorizing facts and getting a "feel" for how recipes work. Many chefs study chemistry to better understand how various cooking/baking processes work. A few might even get into the physics underlying the chemical reactions just to satisfy curiosity. But you don't need to keep going into subatomic particles to have lost the feeling that cooking is based on mysterious unknowns.

For my personal interest, I've learned about compilers, machine code, microcode and CPU design, down to transistor-based logic. Most of this isn't directly applicable to modern programming, and my knowledge still ends at a certain point, but programming itself no longer feels like it's built on a mystery..

I don't recommend that every programmer go to this extreme, but we don't have to feel that our work is based on "magic smoke" if we really don't want to.
