"Have the robots come for the middle class?"

It's all about faster, cheaper, better. When software/robots are faster, cheaper, better than their human counterparts then the humans will be replaced by software/robots. This has been going on for nearly four decades now. What people haven't been anticipating are the effects of exponential growth in the capabilities of software/robots, Moore's Law. We are now reaching a tipping point where vast swaths of labor can be replaced by these systems, much faster than the displaced workers can be reassimilated into other areas of the economy. This is leading to protracted high levels of unemployment, which we're already seeing our social and political institution's inability to cope. This will only get worse.

This is quickly becoming one of the biggest issues of our age.
