Did they replace the elevator operator with a robot that looked just like an elevator operator? And did they make that robot stand inside the elevator, and pull the lever, just like the old elevator operator would?

No. Of course not.

Because that would be insane. Replacing a person with a robot that does the exact same thing that a human can do, is pointless. It doesn’t improve anything. It doesn’t save you money. It isn’t more efficient. It’s just a very expensive gimmick.
