Very interesting post ! And unfortunately I have read too much about it (Homo Deus, "La guerre des intelligences"...
Therefore I always am the "pessimistic" a.k.a rational. I know politicians (left and right) are really scared of this as they see it coming and are powerless.
The truth is: unemployment will be bigger and permanent for some people. Not to mention technology is making blue workers 'dumber" as seen with Taxi and Waze/TomTom; their cognitive abilities dropped tremendously compare to before.
See ya later !
