How do you know civilizations don’t last long in historical time? Roman, Byzantine etc. yes all fall, but the earth has been continually inhabited by civilizations since they were invented. Our single data point suggests that, so far, once they are created they last forever.
- WJW 4y agoI think it'd be more accurate to say that once created they can last at least 6k years or so. We simply have no data on the survival rate beyond that, because we've observed zero civilizations older than that so far.
