I might get myself back up to nerdy-hacker level, but I don't think I'd bother with 90% of it. So, big-O, command line, control flow, data structures and algorithms, linear algebra, why floats are not real numbers, orders of magnitude in processing speed and data access speed. Probably by watching some online university lectures and perhaps messing with an emulator for some moderately old hardware. Probably not an actual language, even, given what LLMs can do, just enough to follow as pseudocode. But professionally? I'd do something else.
