At first glance, not workable. Is a CNC mill a robot? What is a robot? Who decides? Do we hire some CIS and philosophy professors to study this? Should a hammer be taxed at a very low rate? Does the hardware store checkout robot register the hammer to our SSN? Should self-driving cars get even more expensive? Should the state be a nanny and tax only new robots that come in and take away jobs right now? I think the issue is who owns the robot. You ultimately only tax people. My general feeling is that in general, a pair of persons A and B are unequal in their abilities to use the national infrastructure and access markets. The one more successful at this, as shown by his wealth generation, owes something back that is greater than the one just getting by. And philosophically, this is not confiscation or a taking, but a kind of use tax.
