I tend to agree, since I think that we tend to fallaciously view the addition of technology/industrialism as a positive even when it doesn’t appreciably improve living conditions, with the caveat that the ideal socialist city of tomorrow should probably be apportioned to the population density of the city in question. I wouldn’t want to roll up to densely packed community and force them to spread out in order to chase some idealized version of an Eastern European city.

Completely agree. A lot of Soviet housing was very flawed and while modernism and brutalism can be neat, an entire city with only that architecture can be suffocating.

it doesn’t work everywhere (especially in more dense cities populous countries).

It can result in sprawling concrete jungles like this

In Beijing for instance, you can see older parts of the city being demolished and replaced with high density buildings
