Shaw there is no dispute that advances in technology replaces jobs. The replacement jobs require a higher skill set. This inevitably leaves some behind as a permanent reservoir of unemployed. So far the argument suggests other jobs are created to make up for those displaced.But today the rate of change is so fast that what was true in the past may not be true in the future. To assume the slack will automatically be taken up could turn out to be horribly wrong and there is no way to make an accurate prediction one way or the other. You may find in the future that your smug complacency is somewhat in error.
