Humans make great bartenders, great phone support, great teachers. But when I'm in my room, typing away or something, the last thing I want is a stranger coming in to change the towels or whatever. Keep a human in the front lobby, I'll take the robotic maids any day, please.

That's true, but that's where you have the door sign says 'DND', at least the hotels that I have stayed so far have this 'feature'.

So under what circumstances are the human maids better? If you miss them because you're at the conference, then you don't care whether they're human, robot, or some sort of arsenic-based life-form as long as the room is cleaned. If it's casual smalltalk you want, a hotel maid isn't a very efficient way to deliver that.
