It's awful :(

I saw a video I wanted to share with someone, but it was part of a compilation. So you just search for it, right?

So I searched "cat lets brick fall onto mouse" and got... 100000 AI generated videos of cats with bricks? And cats with mice and cats being rescued by people (like you said). But not the video I was looking for.

We've totally passed the point where real information is impossible to find anymore. Video generation was really out of reach / delayed for a long time, and honestly all of those probably have a digital watermark in them that could be detected. YouTube could have prevented this if they'd have just been more proactive with detection and filtration. A simple "AI generated" and "not AI generated" filter would have prevented this.
