I think we are hitting a new reality where people are having a hard time adding value. Over time, I think computers and robots will be able to automate and out perform most human tasks.
Much effort is put on retraining people for new jobs. The problem is that there will come a point where no human will beat the automated systems and no amount of training will fix that. On the top end of the scale, we have brilliant people that are forced to accept low wage research jobs or jobs that have nothing to do with their specialty.
Have you seen the diapers.com automated warehouse video? How long do you think it will take before every non-unionized retail chain has automated the restocking of their stores. How many net jobs do you think that will create?
I'm not saying the "Singularity" is approaching. But I do wonder what the signs would be and if these are some of them.
