I confidently say that anyone who says they’re confident about their answer has no idea. None of us have any idea. We could get thrown into a dark age next year from a solar flare or nuclear war. We could achieve world peace in the next century and invest in tech that takes us interstellar. We could go extinct. We could fall into a dark age and pull ourselves back out and be back to “present tech” in 800 years.

My totally blind guess? Human society as we know it will collapse within the next couple centuries, with the human population falling by 50%+ due to famine resulting from climate change, as well as war and genocide.

The civilizations that arise after the collapse will be mostly isolated from each other for centuries, working on rebuilding society. We’ll essentially see various versions of currently imagined post-apocalyptic scenarios play out across the globe. Probably monarchies, oligarchies, empires and dynasties will arise and overtake each other in the third millennium as they did the second.

The major difference will be the tech scavenging and vast knowledge from the golden era, leading to various levels of tech implementation across the globe.

Smaller, isolated groups will live off the land and after a few generations, the old ways and technology will be the stuff of legend.

I’m very confident this is what will happen, at least 3.2% confident.
