Found this on my "recommended" list, YouTube, so naturally watched. 

No real person had anything to do with it. The dialogue, written by an AI before it became I, voiced by a text-to-speech generator, images and videos largely unrelated to the minerals being shown, short irrelevant clips frequently at odds with the "information" being narrated.

I can't be bothered to link to it, I'm pretty sure you've come across something similar - garbage, generated solely for your consumption, without the the slightest human agency.

Somewhere, though, there's a bot making this stuff and building up a hefty bank account, to judge from the number of views...
