First, it would be great for you to explain how it is a strawman argument. In my eyes the strawman is comparing one system which has had years of training data and time with a system that has a rough structure, but misses everything beyond it. You'd have to at least give them comparable amounts of training data. Even a newly born baby has already had some sensory inputs in the womb, and starts to have a LOT afterwards.

Second, your Outsider Art is something completely different, funnily enough a strawman. Surely you're not claiming that the creators of outside art have literally never had any sensory input in their lives? Or do you really think that one painter in two timelines, in one blind and in the other not, would paint exactly the same stuff?
