The idea was that all the jobs of someone handling errands for you were automated away and it became a self service thing. Yes, sometimes it is easier to buy something online, no doubt about that but when problems creep in it takes too much of our precious time and from our mental context dealing with things that would be dealt with if those jobs existed. If those jobs existed in higher numbers you could just call a number and a human responds and assists on the other end of the line.
