Can someone who studied at a university be considered self taught ? In my situation I’d say 80% of what I know is because I took the initiative and spend time to learn new skills by myself. While I was doing that of course, I was also pursuing a Computer science degree. But after graduating I cannot say that the degree “boosted” me or it helped me or that it opened doors for me.
But for most people that don’t follow an academic career, I believe it’s a similar situation for them.
