It's telling the name of this repository is "MoneyPrinter"—says a lot about the monetization of videos today. I wonder if the creator has made money on YouTube from this repository. I didn't see any stats in the README.
Unless they have some secret other channel with a bunch of manufactured videos. ;)

It's still better than $0, but then it costs money/time to make and upload good quality shorts that you could spend on full length videos instead.
Because shorts are well, short, they can't run ads on them the same way they do for full length videos, which apparently hurts the revenue potential.
On the other hand, what's the revenue of a short? They've got to be pretty worthless views. And of course AI just makes them more worthless.
