Ya, came here to say the same thing and I'm glad others are similarly surprised.

I do think that people who live in the most downtown of downtown areas are more similar to cul-de-sac style suburb dwellers, because there's often a similar kind of implied distance to third-spaces that people want to be in, as if taking the elevator down is equivalent to getting in the car and driving somewhere, and being elevated is like having your fenced off yard in a way, but there's so much more to urban spaces that include skyscrapers than there is in suburbs that include cul-de-sac car centric hellscapes, imo.

If you move to the city from a particularly isolated suburb, please leave the social isolation where you came from, and do what you can to just be present and open to conversation, it's amazing how it feels to be connected to people that you can by on the street because you're both going to the train stop or cafe, and it's this sense of connectedness that makes the thought of moving back to my hometown quite repulsive, despite the individuals who live there otherwise being alright
