Bill Gates: the robot that takes your job should pay taxes

Your computer replaces many things that you used to have to pay others to do.... Should it be taxed like a person, too?

Software replaces many things that I used to have to pay others to do. If we follow the same logic, I should be paying taxes for every little thing that I use software for, too?

I'm filing my taxes for free instead of paying someone. I'm planning my vacations by myself instead of with a travel agent. I'm shopping for a house without a realtor. I even took photos without hiring a photographer! I record and edit videos without a videographer. I learned how to renovate my house without going to a contractor.

Robots are an improvement, and should not be impeded!

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.

Why don't we spend efforts towards making EE/CS a blue collar job? Why tax people who are innovating?
