Of course this is at its infancy. However, I think we can bring about a Roddenberry economy if we can survive long enough to perfect it.

First thing, we'll need unlimited, cheap power. A Mr. Fusion in your basement, or at least on your block, is not too much to hope for.

Second is ubiquitous printers. Whether by nano assembly, transmogrification of elements (unlimited power means you can make any element or molecule), or some other means, imagine throwing dirt in one end and getting out a Rolex or an I-beam or a steak dinner.

Given those, anything you'd want to buy with money from working, you'd just print. Material possessions would become meaningless, as would needing to work to afford them. Manufacturing, transporting, and retailing of material goods, restaurants, etc would go away. Service jobs can be largely automated away also.

So all that's left are thinking and creating type jobs, which might just pay the same as sitting on the couch but be more rewarding.
