Much like elevators, computers are fundamentally better at controlling the system than humans. I assume you ride in computer controlled elevators? Do you understand that they were at one point controlled by humans manually? Did you know that there was a transition period where the computer control elevator was not as safe as it is now? In 50 years the idea of letting a 85 year old or a person walking directly out of a bar control a four thousand pound machine moving at 60 miles an hour will seem insane.

Funfact: all elevators have a safety system invented by Mr. Otis, which haven't changed much since.

So your comparison doesn't make sense.

You are talking about the brake for if the cable breaks. I'm talking about the control system that prevents the doors opening while it is moving, opening in between floors, shutting down if there is a problem, etc.... https://en.wikipedia.org/wiki/Elevator#Manual_controls

Those doors have also safety systems. Formerly, the circuitry to open the door was closed only, when the cabin was in floor level. Opening and closing required constant push of the push button.

(Have some history in elevation control, because we made some standards in the industry.)
