Those who understand binary.
Those who don't.
And those dumb enough to think "nonbinary" is a thing.
With 43 genders there must be at least 43 kinds of people.
There are 11 types of people: those who understand binary, those who don’t, and those who are tired of seeing this binary joke.
Binary reminded me of a funny story.
Many years ago I was at Disney at an arcade in Future World. I was looking at the tic-toc-toe machine. The game displayed a tic-tac-toe card filled with Xs, and 0s. The challenge was to quickly memorize the card and reenter it exactly on the next screen. Two Asian kids were standing next to me looking at the game and I said to them it’s just binary. Converting the rows to numbers reduced what you had to remember by 50%. So we played and killed that machine. People stood around watching us with awe. We cheated. We all took a row so we reduced we had to remember by another 75%. One kid took two rows. An example of distributive processing which was a new concept back then.
