This is true, but I'd say that industrialisation up to this point has already created a swathe of people who have significant trouble finding a job. 100 years ago someone who's capabilities maxed out at wielding a showel cut still find work. Today that's pretty difficult. Granted, must people can up their capabilities by education, training, etc. but not everyone. New technology (including clever software, sometimes labeled AI) will continue this trend. True AI will also replace people, but that'll be way different (http://waitbutwhy.com/2015/01/artificial-intelligence-revolution-1.html http://waitbutwhy.com/2015/01/artificial-intelligence-revolu...).
