The cartwheel fails are pretty brutal, it never learned how to catch itself and break its own fall. Cartwheel is a remarkable demo, I initially thought it was a joke and fake until I saw the blooper reel. Now I half believe it.

Those bots never learn by themselves. It's same as how animations on beautiful LPs don't write themselves. They're all "fake" in that sense, but also "real" in the sense that they would not be just gifs or mp4s but callbacks would be firing and running on customer browsers.
