I think it is interesting that at the end of the video, the researcher says “the brain was freed from the body and could act upon the world directly”. This seems like a strange thing to say. Isn’t using your body a direct way of interacting with the environment? How is controlling your body any different from controlling a robot arm? Isn’t the result(that you are acting in an environment) the same regardless?
