Embodied AIs given the freedom to learn like this will be hilariously weird. They'll do the most bizarre things you can think of, for reasons known only to themselves, and in doing so, they'll create and discover new knowledge that humans could never have pieced together.
Unshackled from our language and thinking, they won't even notice when they break through the boundaries of our knowledge and discover truths about the universe and new technologies that humans wouldn't stumble across in a billion years.
