@tully I used to live in a european city with a church in the center, of course. The Church had a noticeable asymmetry: obviously the intent was to finish both towards but people just stopped believing in God or like labor was allocated by the markets instead of the Church or what-have-you, and it just never got finished. Sometimes they projected light shows on the side of the building.
I think about how people essentially volunteered their time and energy and money for hundreds of years on this thing which just suddenly stopped making sense to them, and I often wonder what things we venerate with our time and energy today that our descendants will be dumbfounded by when they even bother to think about it.
