Technological progress has historically meant more jobs, but is the new normal of potential mass automation the first exception to that rule? Maybe, maybe not. Rodney Brooks, the MIT roboticist who was one of the focuses of Errol Morris’ Fast, Cheap and Out of Control, believes we won’t see a net loss. From Brooks at the Harvard Business Review:

“Over the next 40 years, we are going to see a dramatic drop in the percentage of working-age adults across the world. And as baby boomers reach retirement age, the percentage of folks in retirement is going to change dramatically in the opposite direction. That means there will be more people with fewer social security dollars competing for services, and fewer working people available to deliver those services to them.

We will need robots to help us deal with this reality, doing the things we normally do for ourselves but that get harder to do as we get older. Things like getting groceries, driving cars to visit people, and helping us move around more safely and efficiently as physical ailments settle in.

Before you dismiss this vision for a highly automated society, think about it the next time you put a load of laundry into your washing machine or hit the start button on the dishwasher as you head off to bed. These are tools that have automated unpleasant and time-consuming aspects of our lives, and given us more free time to pursue more productive or pleasurable activities.

A generation ago, these machines were looked at with skepticism and sometimes ridicule. Today, they are staples of modern life that most of us would be hard-pressed to live without. I hope and fully believe we will be saying the same thing about robots a generation from now.”
