Seeing as there's no precedent for a post-scarcity world, and no reason to think such a thing is possible or desirable, I'm not sure how to discuss the topic in a serious fashion. As long as people want to keep improving society, it will require resources, which will produce scarcity.
If you commoditize both thinking and action, even at an average human capability level, then I'd argue that would be a post-scarcity world. At least as far as working humans are concerned.
