The economics of the future is likely a resource based economy, not what we have today.

I think most people would have to agree that as time goes on and technology increases, at some point computers/robots/whatever will be doing ALL jobs everywhere.

You may say "not this job" or "not that job", but the truth is, as long as advancements are made, even at the slowest possible speed, that means the future will eventually be all computers and robots doing the work. Maybe that means 100 years or maybe that means a million years from now. Whatever the scale, so long as advancements continue to be made, the end result cannot be denied.

On a side note, other socialist countries are now talking about having a guaranteed monthly income to all people of their country, whether they participate in the work force or not.
