"The correct approach is to channel automation profits into new enterprises and products. " Sounds good. But could just mean channeling automation profits into more automation and employment of cheap, possibly foreign, labor.
The question is how to get people "relieved of work by automation" channeled into creative endeavors, whether for income or not. Having such people pursue artistic or other creative activities sounds great, but they still have to eat.
Perhaps they'll all be absorbed into new vocations, but I wouldn't count on it. If the need is for data architects, scientists with advanced degrees, surgeons, robotics engineers, etc., we have to ask ourselves how many of the millions replaced by machines could really ever be employed in such positions.
When I referred to "picking up a gun" I wasn't talking about poaching deer, but coming to your door.
