I think the world will eventually reach an equilibrium where humans, and commerce, will simply (because of technology) be so much more efficient / effective than they are today, it will make it possible for governments to be as effective at fulfilling the needs of its people (if not more so) with orders of magnitude less tax.

In the meantime I think the human race will be in a sort of gray area. Maybe it'd be a good idea to implement some sort of "robot tax" for that duration.
