I get what you are saying, and I agree emotionally to some degree. But I think there is a fallacy lying in this sort of thinking. This sentiment appeals to the idea that certain life experiences are the natural order of things and are timeless and shouldn't tampered with. In this case though, shopping at a supermarket and checking out in a line is hardly an ancient tradition that has been the same since time immemorial.

That being said, there is value in daily ritual and routine, and we need to find a way to replace our current ones with new ones that are just as meaningful if we wish to automate all jobs away.
