Make people watch more YouTube.
Crazy videos might become passe or burn people out, at which point the 'formula' will change, but the underlying reality is the same. It's a paperclip maximizer. To succeed at YouTube make people watch more YouTube.
Yea but how do you do that? By making more compelling content than competitors. That's the basic formula.
There's whole subcultures of people doing unboxing videos. People framing existing videos as "unintentional ASMR" (https://www.youtube.com/c/PureUnintentionalASMR)
The point is : it doesn't matter what you upload. As long as it allows Google to show ads to people.
