What happens 5 years later after all the people have moved into it, but Google discovers that the project is not very profitable for them to maintain or that they can't achieve whatever objectives they were hoping to achieve with it?
I'm guessing the #1 objective with this is to create a "role model" for a total surveillance panopticon type of city that governments around the world would then replicate, using its technologies.
I'm also assuming this city would also get "upgrade" to having "always-on" wireless brain scanning technology in the future, so that the company can "better target" ads at you in every moment of your life.
