We made a world populated with objects that reacted to what humans did, but they didn’t interact very strongly. Whereas that isn’t enough, pure discovery learning took us 100,000 years to get to science. So you actually need learning that’s facilitated. And if you can’t make 1,000 good teachers in a year to save yourself, you have to have a user interface that can do that.
