Great Cataclysm

It's pretty obvious that the future cannot happen due to unsustainable advancements in technology. According to scholars, this is to be expected as everything moves in a cycle -- human civilization cycle (from first settlements to collapse from unsustainable advancement) is 10,000 years. At which point the great cataclysm comes to cleanse the Earth and begin us on our journey of pointless growth again. We are reaching that point shortly, so what do you think that cataclysm will be? Jew mind virus? Sun pulse? Great deluge?

But the end of a cycle

Show us the fossils of anything comparable to current technology or it's not a cycle. The current population seems to be unprecedented by far, too, though that would be harder to decide based on archaeological records.

That would work well in a fantasy game, but in reality they did use machines that were much like ours except much less advanced and powerful:
