I am not that pessimistic :-) The story of the last 2-3 centuries is full of examples of disruptive innovations which have led to job market reorganization. The common feature is that the minimum education threshold required to get a job (for most people) keeps increasing. This is a challenge, but not a bad thing per se. Do we really miss the good old times when most people were slaving in mines or in the countryside and died before 40...?
