Zuck wont take meetings before noon because his offline AI starts compounding errors after a few hours and his batteries only last a few hours depending on how much he moves. Having to walk to and from the car twice in a day as well as engage in hours of talking and calculating facial expressions is more juice than they can squeeze into that body frame. I don't get why the designers don't start making zuckbot put on weight so they can jam more cells in there. Maybe its a diminishing returns thing?
