There is a historical parallel for all this: it’s exactly what happened when the spread of “labour-saving” devices transformed the lives of housewives and domestic servants across Europe and north America from the end of the 19th century. Technology now meant that washing clothes no longer entailed a day bent over a mangle; a vacuum-cleaner could render a carpet spotless in minutes.
Yet as the historian Ruth Cowan demonstrates in her 1983 book More Work for Mother, the result, for much of the 20th century, was not an increase in leisure time among those charged with doing the housework. Instead, as the efficiency of housework increased, so did the standards of cleanliness and domestic order that society came to expect. Now that the living-room carpet could be kept perfectly clean, it had to be; now that clothes never needed to be grubby, grubbiness was all the more taboo. These days, you can answer work emails in bed at midnight. So should that message you got at 5.30pm really wait till morning for a reply?
