You make some reasonable points. But the one point that is missing, in my opinion, is if the robot technology age is upon us, then there will be mass displacement of employment. If there is mass unemployment, who is going to buy the goods and services that the robots make?
On the other hand, if robots takeover, then presumably they won't need a wage? Labour can be removed as a factor of production as nearly everything will be free?
But if everything is free, who decides who gets to live in a mansion with a flash car and who does not? Or can we all expect to live rich style lifestyles? Why not, if robots do everything for us?
