You need a prince to make a town in an intellectual sense. Developers want to make money. If they cared about architecture, they'd become architects. I've had so many projects that never came off because they had no sponsor, and not because they were utopian. I just want to build a town that's normal.

The problem was Le Corbusier was a genius and an enormous artist, but he tried to resolve problems to which there is no solution. So the idea to demolish the centre of Paris in order to adapt it to the car - he drew it! - is something not even the most bloody dictators conceived.

Data can generally travel the speed of light unless networks are congested. When there's congestion, usually the cheapest and best thing is simply to add capacity generally, not to prioritize certain sites over others.

For carbon-neutral cities, there are things worth talking about in how our consumption patterns can change - sharing goods, etc. - but those are a fraction of the impacts of transportation and building energy use. If we need to choose priority actions, the most important things are to densify, provide transit, and green the buildings.
