I think we're looking at something fundamentally different, though it does seem kind of like socialism on the surface.
In a true society of plenty, like I think Hatta was talking about, there isn't any real reason for anyone to "work". People can just hang out and do whatever they want. There won't be any real need for central planners, which is one of socialism's biggest flaws.
Its other big flaw, of course, is that people are lazy. If not rewarded for doing a good job, they won't bother. Many won't anyway. But if there's no "job" to do in the first place...
The Native Americans basically had this kind of culture before the Europeans showed up. Part of the justification the Europeans used to steal the land was that the lazy, shiftless Natives weren't "really" using it for much. The thing is, their societies were probably a lot happier than ours, even if they didn't have the same luxuries.
Hatta's definitely correct that this would be a fundamental reorganization, if it's allowed to happen. Our culture has spent pretty much the last 10,000 years building on the idea that food needs to be locked up and then dished out as a reward for work. And wiping out other cultures that prove alternatives are possible.
I don't think we even need the "everything is automated" Utopia if enough people decide to try to make it happen. This may be just pie-in-the-sky nonsense, but I think it's worth pondering.
