Oh, and BTW:
Completely new-designed city society
Resource-based Economy - no money
Robots do menial work (from manufacturing to even building houses) - freeing people to pursue their own interests they enjoy
Resources regulated via computers - no presiding ruling government needed.
Efficient designs for all aspects of society - making all needs localized and easy to acquire for all.
Not designed to solve every problem - designed to simply be a better solution and foundation for society.
I doubt I'll see this realized in my lifetime, but I do believe this is where we're headed.
