Thankyou for that. I've been a bit on the 'good-old-days' side about Buildings and completely forgot about survivorship bias. Just like all the music these days is crap (when we compare to only the best songs that we remember from 30 years ago). I think there might be something in the idea that we did it 'better' for public buildings in the old days (Are there any buildings that cost remotely the amount of National GDP that the Pyramids or the Great Wall did?) -- But I think you're absolutely right when thinking about averages.
