Learning from watching others is actually quite difficult. As Terence said, "when two do the same, it's not the same." No set of pixel observations will be identical. How do you map a third-person view to your own first-person view? You need sophisticated algorithms before 'learning from others' experience' is even an option. We struggle to get robots to learn from imitation. Human children routinely 'over-imitate' because they can't distinguish what part of a sequence of actions is necessary and what parts are optional or can be sloppier and still achieve the goal. Indeed, how do you even know what the 'goal' was? People differ greatly in abilities, preferences, and knowledge, so you would seem to require theory of mind just to begin. (I'm reminded of a point about kittens I saw argued: cats can't learn from observations, and instead, when a kitten 'imitates' their mother, they are actually simply becoming interested in the same object or place, and then independently inventing, by the usual cat trial and error, whatever useful behavior it was.)
