The Google AI isn’t hallucinating about glue in pizza, it’s just over indexing an 11 year old Reddit post by a dude named fucksmith.
@Kurt it could be that the ai pulled info from how they make cheese stretch for the slice lifting on pizza advertisements. They would mix up glue to give the "cheese" lots of stretch. They would also screw down the rest of the pizza and cover the screws with toppings so the slice pulled just the cheese.
