Are you ready for this?

Yeah it's scary. I'm one of those people who does not buy the "Don't worry! We'll automate the sucky jobs but then all of these non-sucky jobs will appear!" argument. Technological advances like these are mono-directional: once they happen it's a permanent change with no going back. There won't be a "horse revival" so to speak (or Pandora's Box reference for those who didn't watch the entire video in the link). This plus continued population expansion is going to cause massive global problems, maybe not in the next year or two but definitely in the next 20. I expect this to lead to a lot of political problems in the mid-21st century.
