this one for sure not, it is more common that I have a deeper understanding of a technology or architecture than most of the colleagues with a CS degree, because as a self taught dev I started like 10 years before most of people that go through college.

> - others struggle with the lack of theoretical background (when optimizing for performance, or deciding which algorithm to go for, etc)

But this is a real challenge. Although I also try to self-teach me CS theory, it is hard to know what I don't know and might be missing in my theoretical base.
