I think that we'll see fundamental changes, but it will be based on cheaper consumer goods because all of the back end white collar labor that adds costs to them will be (for all intents and purposes) free.

But we will see the absolute destruction of the middle class. This will be the death blow. The work week will change, but only because even more people will work multiple part time jobs. We'll think about what we need, but only because we'll have cheap consumer goods, but no ability to prepare for the future.

I think it's bleak. Source: most of human history. We're not, as a species, naturally altruistic. We're competitive and selfish.
