I was nodding along with the first page, but then the second page came out of left field. Hard to take this seriously - what does the ever-distant singularity have to do with dealing with mass economic displacement? One of these is a real problem, and the other we'll deal with when we get there, if we get there. Hard to imagine intelligent machines taking over the world in an energy-constrained future. They have to get smart soon enough to build nuclear power for themselves with our remaining fossil fuel stocks. Or just plug humans into batteries which somehow works...?
