Should we be worried about what the robot workforce will do to society as we know it?

Michael R. Strain thinks so. In Robot workers could tear America's social fabric he notes that the industrial revolution dislocated many workers and created havoc in society which lasted for decades.

We redicule the Luddites for trying to slow progress. But they were the ones who experienced some real suffering.

Mr. Strain fears that the same thing could happen again as the technological revolution advances. He could be right, especially since our schools are doing such a poor job of preparing students for the jobs that are still there much less the jobs that don't exist yet.
