For example, there's a growing industry now of digitizing the zillions of documents, books, photos, movies, art, etc. This is low skilled labor.
Or Apple/Google/Microsoft sticking camera hats on people and having them hike trails to develop maps.
The list is endless.
I may read too much sci-fi, but I am fully convinced that we are heading to a future where most menial, low skill tasks will soon be done by technology and robotics. We have been heading in that direction for quite some time and I don't see that changing. The end result is the near elimination of low skill jobs. This doesn't necessarily mean that people won't be able to find work, it's just that we will need to do a better job at educating them to prepare them for more high skilled labor.
What about people who can't be educated for high-skilled labor? Seems like a taboo subject, but there are a lot of people like this in the world. What do they do?
* edit. These labor shake-ups are going to take place in "high-skilled" areas, too. IBM's Watson can probably be trained to be more talented at illness diagnosis than most MDs. It will be interesting to see what happens to those MDs.
Regarding your second point, I addressed this in the other post, but post-scarcity economics seems to be the best 'thought experiment' as to what a future society would look like. I truly believe that we are entering an age where human labor will become obsolete. It may take a while but, its going to happen.
I think you're correct.
For me, what's difficult is to understand what happens to us at that point...and I guess what happens to us on the way to that point. I can't tell if it will be good or bad (or a mixed-bag) for us/humans.

They give three explanations for the current slow job growth: (1) business cycle lack of demand, needing normal Keynsian stimulus, (2) technology running out of steam in improving productivity, and (3) the opposite, technology accelerating and destroying the need for highly profitable businesses to hire more workers. The authors think technology acceleration has been underappreciated for its effects on suppressing job growth.
I will definitely put that book on my 'to read' list. Very rarely have I been disappointed by an HN recommendation.
We are physical beings with physical needs. We can't live on thin air, we need a basic input of energy and matter to survive. But our society is organized around private property. When you are born, you own nothing. So far, we've been exchanging labor in exchange or property. Once labor becomes valueless, the vast majority of people end up with no means to acquire property, which is essential for physically sustaining life. Something will have to give up, and I'm not placing my bet for the owner class suddenly having a change of heart and sharing their property with the rest of us. Which leaves the majority of people in a scarcer and scarcer world.
