You have to be able to rummage and find the thing you want. And that's still unsolved.

Yeah, because there's physics. We really don't understand friction. And friction is so important. It's what lets us all sit here and things not slipping around. Friction is so important, but it's a very, very complex process. We can approximate it, and there's this model Coulomb friction, etc. But to really get friction right is actually impossible.

If I want to push something across the table, the way it's going to move and react to my pushing force is going to depend on what's underneath it. So if you have one grain of sand... It's going to change it. Yeah, if it's in the right corner, the whole thing's going to rotate clockwise. Exactly. If it's in the left corner, it's going to rotate the other way. But I can't know that.

The robot can't know it. So right there is like one of the great mysteries of nature, right? You don't have to talk about quantum physics. That is one unknowable thing that's sitting right in front of us. Oh, my God. Wow. And we deal with it all the time. So you might say, what do we do? Well, we kind of compensate. When we reach for a glass, we don't just reach our gripper right up to it.

We scoop it up. We're almost anticipating the many different ways it could go wrong. Exactly. We haven't figured out how to do that for robots yet.

It's both. It's largely software because we don't have the sensors. We don't have the control. We don't understand the models of physics. But I also think we need better grippers, too. But that's a whole other story. But the bottom line is that we're far from anything approximating human level performance. And there's been so much hype. And that's what I worry about.

I really do. I think we're on a collision course with a kind of bubble that's going to burst because people are expecting that we're almost there, especially when they see these videos. OK, great. Tell me about these videos because you watch them and you think. We're there. And this is a big problem.

Right. Okay, the first thing to ask is how many takes were required? Many times they get to work once, and that's the video they show.
