I agree with the premise of the article but there’s also some survivorship bias at play. We know about (and don’t knock down) the particularly beautiful older buildings. If you go to New York City there’s beautiful stuff from the early 20th century (think Chrysler Building) and plenty of unremarkable stuff still standing (think pre-war walk ups). Maybe one in a hundred of the older buildings is remarkably beautiful.…
1) There are many older cities in Europe where the entire city center is beautiful. Paris, for example, or Tallinn. These aren't just rare 'survivors.'
2) Where are buildings from the last 40 years that will be the 'survivors' of the future? In NYC alone dozens of beautiful buildings were built in the 1920s and 30s. Where are the dozens of modern equivalents?
