I think GPT-3 is especially suited to triggering your pareidolia in this particular format, because we know that presentation slides often need an accompanying speech to give them context/meaning; and without it, they have a tendency to be just this disjointed.

So, when you read "presentation slides" like this, the same mental algorithm that tries to piece together what "the speech" was for a normal slide deck, kicks in in your brain, and gives you some valid-seeming ideas.
