A doctor I've been seeing told me she loved to operate (and from the look in her eyes, I believed her), before quickly reassuring me that she wouldn't do any unnecessary surgery. So I'm pretty sure she would call it fun :)

Programming has gotten far easier though in the last few decades due to GC languages, open source libraries and package managers. It really is feasible for smart non-specialists to program computers now.

I find the technical and ethical complexities of coding fun though.

There wouldn't be a market for puzzles if some people didn't get their rocks off on thinking.
