I (ggp) actually don't agree, contributing proper mic boom holding to a project you find important and valuable and meaningful can be meaningful. Every contribution is meaningful.
I guess to me the crass eyeball-harvesting of MrBeast seems like exploitation of everyone involved with the only meaningfulness involved being profit. But I realize based on stickfigure's response that different people find different things meaningful, fair enough. Which is different than saying "just getting lots of money is meaningful for me" -- that is a different axis than meaning, and I'm unlikely to be swayed otherwise, although some people don't need meaning they just need money. It was hard for to imagine anyone is doing it for anything but the money at MrBeast, but different people are different and some of them are hard for me to imagine, fair!
Ever watch the Jackass movies? I know plenty of MFA-toting snobs that think it's high performance art. And I don't disagree.
I read the PDF; profit wasn't on the list of KPIs. In fact there was quite a lot of invective against it; he'll kill expensive projects just because he didn't think the quality was good enough. Of course $$ is related, but the focus really is on the eyeballs.
I worked in porn for a while. I found the work fun and meaningful. Not every mission involves saving the world.
Isn't what makes something meaningful in the eyes of the beholder? It might not be sending rockets to mars or curing cancer, but if you perceive it as meaningful, then it is.
