revolution is changing that. you have warned me not to get too close. it does look a little bit hazardous. this robot dog hasn't been programmed to walk. it's learning by itself. it's called reinforcement learning. what we've done here is, we've given it this task to try to kind of stand up and move forward. when it does well, one of the computer scientists gives it the digital equivalent of a pat on the head. i can see it's doing better and better. it's strong. i try and put that in its way, and it's stronger than i am. yeah. have you trained it to make a beeline for me? uh-huh. i feel like i'm battling the ai here, and the al's winning. in just a few hours, it's moving around by itself, even coping with the unexpected.
