Yeah, it seems sort of obvious in its own way. People like “the primagen” on YouTube are really entertainers first and educators second. The pitch is something like “I’ll pretend to teach you something, and you’ll pretend to learn. But actually I’ll just entertain you by being a goofball for 20 minutes. You don’t have to do any work, and afterwards you can walk away pretending like you learned something”.

I suspect in his case he might actively dumb down his skill level for the stream, so he doesn’t scare away the junior devs.
