The article is a bit weird because as far as I know Stockholm hasn't become much more walkable, or bikeable, in the last 15 years. (They have spent billions on car infrastructure however). Copenhagen is much superior in this regard.

There seems to be a growing trend of talking up Stockholm (maybe because of the insane housing market), while not much have happened really. Most of the "ideal" development of Stockholm seems to be from pre-'90s, including all but one subway station.

In the last 30 years the main developments have been malls and "soulless" residential areas in the spirit of "Hammarby Sjöstad". [https://en.wikipedia.org/wiki/Hammarby_Sj%C3%B6stad].
