Just the tip of the iceberg that is coming to the 40 hour work week. I think that we can now assume that the pace of introduction of robot replacements will accelerate. A prime target should be the education system where significant potential upside exists as a result of the failure of the current system. The 28 hour work week will become a reality for those who manage to keep a job and professionals will migrate towards "independent contractor" status. Very interesting times are coming.
