The way I view this as a net-gain is that AGI agents will be able to have innovation on improving themselves (exponentially?) and the whole world. They very well may be the path to a utopia.
Task 1 for AGI: Optimize your own system so you don't cost 50 million dollars to train.
If I had to speculate based off my experience at other FANG companies, the videos still exist in the Youtube infrastructure somewhere to allow for the possibility of a human intervention to restore them (For example, to allow for recovering from a system gone haywire or just to give time for manually reversed decisions).
That said, I'd also guess there's a countdown timer before they get deleted permanently.
I hope you can get a human from YouTube to talk to you.
It may benefit you to post a link to the youtube channel so someone can proactively investigate. Lots of google employees read this forum.
Except they showed their AI the 3 most important frames (rock paper scissors) and not the hundreds in between.
