Now we are getting into the quantum physics question of if the universe is discrete or continuous. Which seems to be unsolved.
So I guess that’s my answer. If the universe is discrete then there are finite genders, and if it’s continuous then there could be infinite genders.
My favorite project was C++; it was big, it was complicated, there was a massive team working on it, I got to work with high level abstractions while occasionally dealing with really low level concerns.
It was really hard, but now writing code in every other language I’ve worked in has been really easy.
