"The designs revealed today for the city's vertically layered communities will challenge the traditional flat, horizontal cities and create a model for nature preservation and enhanced human livability,"
The reaaon is that those houses are not built in the desert. Your point is invalid.
You have to protect the plants from the drought and humans from sandstorms. You
can not cover a km wide 100m tall city, it has to be 200m x 500m. (numbers are arbitrary, but it has to be compact and as always, biger is cheaper, if 200x200 already covered "up" it is.
I suppose so? The Shanghai maglev train [2] might be the only high-speed maglev in operation [3]. The train has a cruising speed of 431 km/h, but averages 250 km/h in actual operation — covering 30 km in 8 minutes with no stops in the middle.

On the contrary the article says this..
"The designs revealed today for the city's vertically layered communities will challenge the traditional flat, horizontal cities and create a model for nature preservation and enhanced human livability,"
There's a reason houses aren't built like grain silos.
This article and digital rendering has seemingly managed to convince you otherwise.

But of course the whole idea is just "clickbait".
It really doesn't seem practical though. Instead of a 20 minute metro trip to the other side of town, you're looking at a 2 hour ride...
No the article says it's a 20 minute ride to the other side of the city.
Next you're going to say that a sky bridge 300m above the ground with a shin high guard rail is impractical.
As described in OP:
It would take a 500 km/h train to cover 170 km in 20 minutes. I think only maglevs [1] approach that speed.

It would take more than 20 minutes if it had to stop in the middle. So, I guess it stops only at the ends?

The article is wrong
