At various points throughout history the nature of work has radically changed. We saw this with the industrial revolution and also at the turn of last century. At one stage in the late 1800s there were up to 200,000 horses in New York providing transportation. Managing horses was one of the biggest industries around. By 1915 they’d all but disappeared, having been replaced by mass-produced cars. Not only did people survive, they adopted new industries and continued to thrive.
