Hothouse Earth leading to extinction event. Likely no humans and little other life. If Earth is lucky, it might cool down eventually and another chance at life will occur.

Probably mostly dead

We will all either be transcendent uploaded cyber-furry collectives spread across space governed by dyson sphere gods (or some variant of that).

Or we will be dead.

The Fermi Paradox kinda points to the latter.

OA is a somewhat reasonable extrapolation, though. Its optimistic, but even then, they almost didn’t make it.

Very different, and what kind of different will depend heavily on what we do now

All land is bare rock and the oceans are filled to the brim with algae and jellyfish. Too hot and dry for anything else.

There is no way you could’ve extrapolated today’s world from shortly after the last ice age, you cannot extrapolate 10.000 years into the future from now, ESPECIALLY since progress (in every area) has accelerated to unprecedented speeds.

Warm and stormy

A Starbucks data center on every corner.

Pretty hard to predict. 10,000 years ago humans were just starting to figure out agriculture, animal husbandry, and pottery. Today, technology is advancing exponentially. If we keep up this trajectory, we’d basically be gods with unfathomable control over ourselves and our environment. If something interrupts this trajectory, we could find ourselves back in the stone age, or extinct.

Mars. It’ll look like Mars.

We either figure it out and leave in a solar punk society or it turns out to be some dystopian hell scape world.

More diseases in nature, bugs and fungus for food. Fossil fuels will be depleted, which made it possible to feed an extra 7 billion. Existing farmland will have accumulated salt. Refined materials (steel, rubber, plastic, glass) will be much more expensive to make. Concrete would be replaced with clay.

Yabba-Dabba-Doo!!

Cat people have taken over the world
