…There's the question of where the software will be, and then there's the question of how many physical robots we will have. How many of the robots you're training in Physical Intelligence, these tabletop arms, are there physically in the world? How many will there be by 2030? These are tough questions, how many will be needed for the intelligence explosion. These are very tough questions. Also, economies of scale in robotics so far have not functioned the same way that they probably would in the long term. Just to give you an example, when I started working in robotics in 2014, I used a very nice research robot called a PR2 that cost $400,000 to purchase. When I started my research lab at UC Berkeley, I bought robot arms that were $30,000. The robots that we are using now at Physical Intelligence, each arm costs about $3,000. We think they can be made for a small fraction of that. What is the cause of that learning rate?…
