I don't follow or watch Mr Beast videos, but from what I've seen, they are largely driven by a money fetish and as far as "creativity", it feels on par with the more boring "What would you rather" conversations I had in middle school.
Maybe he has unlocked the key to virality by vigorously analyzing data, but looking at his videos, at a glance, it seems to more be formulaic, predictable, and simply having an actual budget that sets it apart (if it is actually set apart, as I find it hard to tell how much of it is others copying his work versus hius work being unoriginal).
On the positive side, YouTube has brought the world closer. We can access videos from nearly every corner of the globe, giving us insight into how others live and interact in their environments. Additionally, it's become an incredible resource for information. If something breaks in my home, I can probably find a video explaining how to fix that exact model. While I'm not old enough to have "adulted" without YouTube, it’s amazing how much you can learn from it.
