Jon Perry has written an interesting post listing some strategies for dealing with the Technological Unemployment Problem.
The Technological Unemployment Problem is the issue of technology replacing humans to the point that there is massive unemployment.
My own feeling is that there will be an increase in unemployment, which will mean a change in society. I think that a number of the proposed strategies will happen:
We will become a “Frugal Maker” society. Food will be grown using efficient techniques such as aquaponics. We will be using machines to produce goods for ourselves. People will use technology to reduce their discretionary spending.
People will also be augmenting themselves with technology in order to become more productive. You can see this already with smartphones and tablets.
Unfortunately I think that these changes will be accompanied by wide-spread social unrest.
