10-15 minute videos are usually nothing more than an extended /r/todayilearned post. I'm not interested in learning some new trivia, I like it when the videos are structured and detailed in a way that makes it flow like a narrative. Although some creators (like Quinton Reviews) pad with unnecessary fluff, most of the really popylar ones (Hbomberguy, Lemino, Jenny Nicholson, Lindsay Ellis, Summoning Salt) don't.

You could argue that anything except the thesis statement is a "waste of time," but the videos are for entertainment at the end of the day.It wouldn't entertaining for someone to say "The Oof sound in Roblox was invented by Joey Kuras for a game called Messiah. Tommy Tallarico says he made it but he probably didn't." then the video ends.

What is fun is watching a long deep-dive pulling apart all the ridiculous lies and exaggerations of a fascinating narcissist like Tallarico.
