Not new, but this is a great critique of The Line project in Saudi Arabia: https://youtu.be/2b7uMJkvS0o?si=mfMd-U-CtV1RX3Oh
So many wealthy people these days want to build utopian cities of one sort or another from scratch. The green rhetoric behind these projects is commendable, but almost universally the proposals fail to grasp what makes a city livable: organic human community and character.
There are ghosts lingering in any human settlement--whether you welcome them into your community's life and honor them determines whether your city* develops a soul or becomes a ghost town itself, haunted by failed ambitions.
*this is true of towns and smaller communities as well as cities--it applies at any scale of settlement TBH, even individual houses
The beauty in cities comes not only from visionary architecture and planning but from the many layers of a kind of palimpsest made from rebuilding and revision. This doesn't have to take centuries--even in a brand-new development it can be achieved by incorporating elements of the natural landscape that existed before humans moved in.
