I don't think we've reached the 'singularity' or other pivotal event that would translate into a major shift in economics. Nothing will change the basic supply/demand equations until some part of the equations involved are truly free or infinite.
Any gains in efficiency and production just go to higher profits for owners. Why would anyone volunteer to pay someone the same for 20 hours of work, that they were previously making working 40 hours, just because some new tool came out that makes the worker twice as productive? The worker will only get payed based on the demand for his product. The boss would never just give him/her more just because they became more productive, unless there is a corresponding increase in demand for that product.
Think free energy / free work provided by self-replicating nano-bots (snap your fingers and a complete house is built in one week out of dirt by tiny robots who can transform any atom to another, etc..). Strong'ish AI machines handle most hands-on service industries, like cleaning, waiting, basic health care, etc..
At that point in time, the only thing of value will be raw material and truly subjective pleasures like artisanal food/wine, art/music.
Now that would be a shift that would fundamentally break supply/demand.
