Just a few more links I have come across recently that would be good to keep here as background:
Some more about AI and technology – http://theleveller.org/2016/04/we-need-to-be-ready-for-the-next-revolution/
Crisis of Capitalism https://www.wearecognitive.com/our-work/crisis-of-capitalism (lots of great stuff here)
Slightly unrelated but about changing way we are educated relying on technology
I need to search for examples of pre-agrarian societies toiling a lot less than us lot – I think I recall there being a section in Mothers and Others by Sarah Blaffer Hrdy.
