Even then, I’m skeptical because every time the AI community has tried to cross the chasm from the digital world to the real world, they’ve run into 10,000 problems that they thought were paper cuts but, in sum, add up to you losing all the blood in your body. I think we’ve seen this with self-driving cars, where very, very promising growth rate, and then an incredibly grinding slow pace at getting it to scale.
I just read a paper two days ago about trying to train human-like hands on industrial robots. Using reinforcement learning doesn’t work. The best they had was a 60 percent success rate. If I have my baby, and I give her a robot butler that has a 60 percent accuracy rate at holding things, including the baby, I’m not buying the butler. Or my wife is incredibly unhappy that I bought it and makes me send it back.
As a community, we tend to underestimate that. I may be proved to be an unrealistic pessimist here. I think that’s what many of my colleagues would say, but I think we overestimate the ease with which we get into a physical world.
