Survivorship bias. Buildings with brilliant architects and engineers are more likely to last through history and/or be preserved by their fans. So the expectation would be, when looking at the best products of the past, the average IQ of their producers would be above the average of both their time and ours.
Also average IQ at any given time is 100, by definition. I believe this post was trying the classic "all contemporary creations are degenerate" take on architecture and art, but not doing so very eloquently.
Hah. There are absolutely people here on HN right now who would be happy to live in a world of quiet labor and pilgrimages and digital disconnection.
Other lifestyles needn’t be romanticized more than our own, but they also don’t need to be demonized. Keeping yourself safe and fed isn’t a big stress for most people through most of history, yet does get quite hard for some people some times even now. The difference is mostly just textural.
We are no longer a hunter-gatherer or agrarian society -- people of olden times would fare as well in our society as we would in theirs. Maybe they could be more self-sufficient, but modern society is free from tending to our fields or bison or whatever so we can have more time to do things beyond just subsistence farming during all our waking hours.
