I too, for a related but slightly different reason. Human interactions at work, even within the limited social confines of the relationship between a service professional and a customer, is really important to society. Even if new technology creates an equal number of jobs in the Amazon 'Mechanical Turk' style as the traditional roles lost, it's not healthy for anyone to repeatedly do the same task alone at a desk for 40 hours a week. I suppose you could some up my belief as: +1 to secretaries, -1 to typing pools. There's a huge wealth of folk songs from around the world that were sung at work, serving both to coordinate the workers' movements and to strengthen the social bonds among them. See for instance the Scottish 'waulking song'. Singing/whistling at work is pretty rare now anyway, but the complete lack of any constructive social interaction in some recently-invented jobs is a new low.
