Tech Insider recently released a video segment that i'll link below. It displays a spider like subject as well as a humanoid subject. The subjects go over an obstacle course again and again and each time it fails it learns what movements work and what movements do not work.
That's amazing.. scary too! I read the other day how some researches (maybe at Google too?) had two AI's interact with eachother and apparently they invented some way of communicating and the researches quickly shut down.
that's crazy!! terrifying actually
