This is not an AI generated channel. This channel has been posting videos in this format for 6 years now, (eg https://youtu.be/1sjPGo_6unY) long predating AI made infotainment.

The visuals are comprised of stock footage and artist impressions, but they’re not AI generated; you can see on some illustrations he credits the artists.

And they only post a few times a month; AI channels post several times a week.

This format (visuals and narration) has been common among science topic YouTube channels for over a decade. Unfortunately AI spam channels have appropriated this format and now legitimate channels are being incorrectly confused with them.
