It starts to become a problem once you’ve replaced public infrastructure to a sufficient degree by private infrastructure like waymos that avoiding to use them starts to seriously inconvenience people.
So waymos means less busses/trains, which means a bunch of people stuck in the middle - they would prefer to take a bus or a train but the service is poorly maintained so they are forced to take a waymo.
Public infrastructure has been run by private companies for a long time.
That has changed. Networked cameras and AI means that cameras can be constantly monitored: license plates logged and mapped in realtime, faces scanned and profiled, symbols and objects detected.
I have no problem with calling the cops on someone with a gun. But that same kind of tech can (and has already been) seamlessly be turned on protestors, journalists, political opponents, union organizers, and ex girlfriends.
Networked cameras with ai monitoring is begging for totalitarian oppression. A cabby calling the cops because I did something shitty in their cab is not.
