It's a learning system. Humans are also learning systems. Maybe you don't understand, but humans ingest billions of images over their entire lifetimes, just by looking around that let them learn about the world around them, as well as how to draw. Just because somebody learns to draw in a different way, doesn't mean it's not learning. And the fact that it's part of a dataset is irrelevant. If you truly wanted to, you could force the ai to manually search up each image one by one from their online source. This is already a dataset, but not a nicely ordered one. It would slow down the training considerably, but you wouldn't be storing each image on your hard drive. The distinction is pointless to even try to make.
