I think that in 10 years something too coordinated will not happen, but the fact that technology will surround us at every step is certain. Maybe cars will even start flying lol
It usually takes a long time to happen although technology is improving step by step there is a government ban on work. The lands are under the control of the government and from here the corporations take taxes and subsidies so creating their own city is nothing but imagination.
The first thing the government needs to prepare is the infrastructure for the new city because, without that, the new city will not run better than the other cities. The government needs a lot of money to start to build that new city and yes, the tax can help that make a new city happen. And that will need more than 10 years if the technology still develops and needs to be invented. But it will happen in the future and maybe we will see something like in the Star Trek movie.
