Since the beginning of the Industrial Revolution, technology has eliminated some jobs and created entirely new ones. There are not many buggy-whip makers these days, nor a plethora of coopers hand-making barrels. But there are millions of software developers and sysadmins - jobs no one would have imagined possible a mere seventy years ago. It's easy to fixate on the lost jobs, but much harder to envisage jobs that have not yet sprung into existence. Yet those invisible jobs are the future and we should be thinking about how we want them to function.
