I want elevators that have both. The buttons outside the elevator to help scheduling. The buttons inside so that anyone that walks into the wrong elevator can still tell it where to go. Then we mount cameras and other sensors in and outside the elevators, and we record statistics about how well the system is working. We use facial recognition to recognise our guests. If you take the wrong elevator three times in a row the concierge will take a wet towel and whip you one time on the back of your thigh.
