From the 1x world model: https://www.1x.tech/discover/1x-world-model

These videos of a humanoid watching itself in a mirror are a cool test of a “self” model. The robot’s world model tries to predict the next visual inputs. It can predict its own movements from a first-person view but doesn’t map the mirrored body to its own, and thus, the mirrored view doesn't match. Would love to see these examples scaled up into a larger benchmark about models of self.

Many point to cumulative culture as the distinctive feature of human intelligence. Now, a new theory argues that our success comes from the way that cumulative culture is uniquely open-ended, i.e., we can accumulate novel technologies, languages, moral systems, or nearly anything adaptive. It's this flexibility, rather than just the accumulation, that differentiates us from other animals.
