I don't think that our current leading-edge technology has really gotten enough penetration to see how it is going to change things. And I think that within two or three decades, the capability of those machines/AIs is going to increase by a very great amount.
It is almost of a leap of faith to have this worldview, but I have seen so many powerful AI wins recently (self-driving cars, Jeopardy bots) changes and advances in actual artificial general intelligence, that I think we are going to see "strong" AI within two to four decades.
Even if that doesn't happen, the leading-edge machine-learning and automation robotics is only starting to be deployed.
Within a few decades, I think there are going to be so many jobs replaced, the current structures will be inadequate.
And as more and more jobs are replaced by deep learning systems and/or better natural language processing, even before we get to "strong AI", I don't see how the structure is going to accommodate that.
The problem is that within not too many decades, I believe, almost _everything_ people do can and will be done better by AIs/robots.
So whether we can keep our jobs is not even really our main issue. What we really need to think about is, how can we stay relevant in a world where AIs that are twice as intelligent as people are common? The answer, I believe, is to incorporate those AIs within our bodies.
Ultimately to buy into that line of thinking really requires a significant change in your worldview, which is why I think a lot of these discussions aren't really fruitful. It comes down to your beliefs. (Everyone has beliefs, whether they are boring and reassuring, or "crazy" sounding like me.)
