I think that I have posted it here as well.
Basically until there is a true AI, automation creates temporary dislocations and (in the long run) generally improved standards of living. This should start to reverse drastically when machines capable of similar training flexibility to a human are available for a few years human salary. A few years of Moore's law after that could spell one of the most important transitions in human history...
I plan to expand on these thoughts around Halloween. :-)
Cheers,
Ben
