A fun alternative time line to think about would be if the romans had progressed, had depleted all coal and oil resources, leaving us today in a postapocalyptic wasteland, having the knowledge how to build an advanced society, but lacking the ressources…

Presumably it would have happened more slowly, as the world population was less then. Though, maybe that wouldn't have actually made that much difference, as the rapid population growth of the last few hundred years is probably largely the result of technological progress (specifically, increases in farm output and modern medical technology). If there had been a population boom during the Roman empire, they might have been able to consume the world's fossil fuel resources pretty quickly, and with predictable results.

I would read that book.

Anathem by Neal Stephenson has some of that vibe. If you haven't read it, I'd recommend reading it without even glancing at the Wikipedia page or plot synopses to avoid conceptual spoilers.

It doesn't have tone in common with post-apocalyptic fiction. I'd call it "alternative future", not that it's easy to pigeonhole!

It absolutely is germane to this conversation and thanks for reminding me of it.

I think HN would enjoy it very much. It's an astonishing novel. Read it!

"A mote in god's eye", by Niven & Pournelle covers a very similar setup, although not on earth. It's also quite good.
