“So I imagine that there's some distribution over possible environments that the robot could find itself in when it actually goes out into the world, right? So maybe it's going to go to houses and the houses are all somewhat different. And once I put that program in the house, maybe it's going to do some estimation or learning. It's going to adapt to the circumstances it's in. My job is to find a program that does a good job of adapting in all the environments that might find itself in.”
