Building New Cities

Won't work. Most popular cities today have grown organically, and were not designed by a small number of people.

Yes, many big cities are (state-sponsored) trying to grow vertically instead of horizontally.

Architect here.New cities normally don't work as expected: cities are like a living organism, they need time to mature. Lots of research was already made on these subjects (most people are not aware of it) and even if some ideas are really good, status quo makes any change very difficult.By the other hand the knowledge fronteer is still near on building cities in different environments/planets, so IMO, YC should go on that direction instead.

Aren't we talking about urban settings? Building cities from scratch?

Building a city seems very... central planned. Normally these things should grow organically. Unless maybe you're in China or North Korea.

Yes, bad urban planning is problem.

you don't have to build new city from scratch just do city planning and dedicate one outside part of city to high density, high tower residential buildings then let me people decide where they want to live.

So? That's a result of city planning that could have happened in the US as well.

I have noticed that the main failing of planned cities seems to be the megalomania and misguided sense of organization trying to decide how it will be used specifically - often out of some misguided ideal of efficiency instead of leaving it to the people to decide. It brings to mind having a single restuarant outside every cul de sac and expecting residents to go only for the nearest restaurant.Sanity calls for embracing the non-deteminism.
