The self-taught path can also lead to another kind of deficiency, which is someone who knows all the concepts but doesn’t know how to talk about them efficiently. This ends up being the type of person who spends 5 minutes describing a component of their design where items are stored based on a key and can be looked up by that key so another process can stash and retrieve those things rather than recompute them but the things only stay stored for a certain amount of time or based on some other criteria like how much space is available or how frequently they are fetched and—- and you cut in and say “so a cache.”

I used to have a particularly brilliant (not sarcasm; he really was brilliant) colleague who “invented“ lots of things that had already been invented and would have saved a lot of time by just bouncing things off others who would say stuff like “oh, so it’s RPC” or “oh, so like a distributed queue” and stop him from reinventing the wheel.
