Nerds. Some overlap with geeks? It's sort of slang. People who like knowledge and/or people who like learning about a couple super specific things. Like you could have a horse nerd or a math nerd or even a fitness nerd, which is not necessarily the same thing as a jock.

Ohhhh but that's a good point. These guys don't like thinking about troubling stuff, if it stopped working, the new robots might have forgotten it entirely.
