> Please, I thought somebody will mention some arcane, rare topics that self-taught person may have no opportunity to hear about, but definitely not those really popular topics.

Agreed. These are it something many “self taught” developers I know have never heard of. For fucks sale with all the complaining about things like leetcode and other interview styles. do you seriously believe self taught people have never heard of these things?

Unfortunately, it seems in recent years “self taught” became synonymous with “some guy who decided to do a bootcamp because he heard there was money in learning to code”.
