As robots liberate us from old tasks so new and productive uses of our time will emerge

Moore’s Law—the idea that computing power doubles every two years—means that robots have enormous potential to transform many human industrial activities. Classic blue-collar jobs will disappear or be taken over by machines, as robot miners and driverless cars replace humans. White-collar jobs will be threatened too. Traditional journalism is already being eroded as smart software generates reports on the weather or company results. Lawyers are being replaced by machines able to scan legal documents.

This has resulted in significant disruption in the job market as the manpower employed in particular industries shrinks. All the technological advances since the industrial revolution have led to some job losses. A century ago we had half a million miners digging coal; now there are a few thousand. At the start of my career in the Treasury we had staff in typing pools; now they are a thing of the past.

The disappearance of these jobs may have been painful for individuals and the places left stranded by changes in the job market, but it did not lead to long-term unemployment. Instead new jobs were created—from personal trainers to software engineers. We are told by those sceptical of the robotics revolution that this time it is going to be different, but I am not persuaded of that. Human wants are infinite and as robots liberate us from old tasks so new and productive uses of our time will emerge.

My colleague at the Resolution Foundation, Gavin Kelly, has investigated the pessimistic interpretations of the Organisation for Economic Co-operation and Development (OECD) and others, and shows that they ha…
