Because you can just have actual local people do it right there and then? The point of a robot is to not interact with other people, presumably they will be much more expensive than having someone come over for a few hours a week to clean - the whole appeal is there's no other human involved to coordinate or be nice to.

This is what happens with "autonomous" delivery robots that are operating on London campuses.

They are actually controlled by "robot operators" in Estonia, though officially it's "AI".

That being said, every day it's getting a little bit better.

Because one remote overseas person can watch multiple camera feeds at once which should make the cost of a human-in-the-loop more palatable.

Liability.
