There are a TON of AI generated videos on YouTube nowadays. I'm surprised that this guy is surprised. Two seconds into the video which he uses as an example, you hear one of the most popular AI narration voices around.

It's stopped bothering me now, because some of them are actually interesting. I've recently spent far too long watching AI generated history videos. ElevenLabs narration plus heaps of grainy public domain video clips stitched together to roughly meet the narrative.

They're not bad. IMHO.
