It only delays the inevitable. The minimum wage for a person is about 2000 calories per day. Getting a robot from "competes with $15/hr" to "competes with 2000 cals per day" is only a few doublings when we're dealing with exponential technologies.
Not really. I can see them eventually having a McDonalds run by robots, but the Ritz will never be - and if McDonalds has robots, that's all the more reason for the Ritz not to have them.
