Why not both? You make it sound like only as long as we don't have an automated hamburger maker we should respect the people who cook our hamburgers, but not afterwards. Progress in any field is usually a function of amount of money poured into it, if the margins for hamburgers were large enough, ie. no cheap labor or higher food prices we would have invested more engineering effort into making smart enough robots that make hamburgers and probably by now have them being made automatically.
