Once you start to see buildings from an era, which are generally considered "ugly", reach the point where they need major, expensive overhauls, and face systemic demolition, then they become "historic" and worth protecting.

This happened 50 years after WWI when we started systemically removing pre-war buildings because they were "ugly, ill-suited to our needs and overflowing with useless decoration", and it is happening now, 50 years after the rise of Internationalism and the over-abundance of it's stark, simple aesthetic.

The way many people look at early modern buildings today, with contempt and disdain and an opinion that they're ugly and should be demolished, is nearly identical to how many people 50 years ago looked at buildings constructed in classical styles.
