im not trying to take anything away from our biologies (other than speed) Lots of things we don't know like how well some animals are navigating. We would like to believe they navigate by magnetic fields, and that's about as good as we know, which is pretty bad. We are fueled by things like carbohydrates, oxygen, water, easy to forget how amazing this is. Its only when we try to build the robot equivalent we realise how efficient nature actually is.
