But did the elevator operator get replaced by a humanoid robot pulling the lever of a formerly human-operated elevator?
That's what they person before you was referencing. In most situations a simple computer-controlled mechanism is enough. If that's not enough, a non-humanoid robot trumps a humanoid robot. And in situations where a humanoid shape is really necessary, human labour is really cheap.
Humans don't have their shape because it's the perfectly ideal form, but because evolution always only iterates on what it has.
Btw: automatisation happens because either using a full human for a simple task is overkill (e.g. your elevator operator example) or because humans really aren't the optimal shape (e.g. using a robot arm to lift a car during production). If a humanoid shape is required, humans will do the job.
