Have to say Rainbows End is one of my favorites. It's got everything AR, VR, AI, Social media/belief circles, mass behavior manipulation, reverse aglng etc etc. I felt like I was looking into the near future.
In the same vein that 'True Names' covered the last 10-20 years with AI, Anonymity, cyber crime, hacking, and virtual reality, I think 'Rainbows End' is our next 10-20 years.
