Heard a bit about that on NPR yesterday, Lunican. Very interesting.
I think where Jeffrey gets it right is in projecting there will be a greatly lessened demand for overall labor, skilled and unskilled. This includes many 'creative' type positions in the near future.
In the future, controlling the means of production will be as important as ever. It might be the case that a new socio-economic system is required, or a massive reduction in population. (By what means? This is a scary question... and if I have pondered it, so have those who are much smarter than me, as well as more willing and capable of enacting policies to such an end)
Will the new technology serve all of mankind, or just a few? If history is any guide, it doesn't bode well for the masses. (unwashed or otherwise)
