My best guess is that we will be living in habitats on Earth with a significantly smaller population.

Our habitats will probably be underground and small, to give us better environmental protection. We probably won't own much of anything. Everything of significant value will be rented or leased, so that the government can maintain tight control over every resource available.

Most of our power by that point will either be nuclear fission or fusion. I expect that the surface weather will be too hostile for anything like solar, wind, ect.

I'm going to speculate that most populations along the equator will end up migrating towards the polls due to the extreme volatility of the weather. It'll either result in a horrible war, or countries dissolving as their populace suffers due to famine or environmental disasters.

We'll grow most of our food in hydroponic hot houses. I don't think we'll be eating meat from animals regularly. The majority will be vat grown, and "natural" meat with be a rare and expensive luxury.

Healthcare will be amazing, if you can afford it and if the resources to make drugs are still available. Peptide-based medications will be used to treat a lot of common health issues. Gene editing will be common for genetic diseases. If you need an organ replacement, they'll be able to grow you one. We'll probably be able to live a lot longer, with a higher quality of life.

While we're holed up underground, humanity will likely pursue the stars earnestly. If we're lucky, it'll turn into a collective effort between many countries. If we're unlucky, it'll be a bloody scramble for resources and scientific intel.

Either way, I think humanity will still be here in 10,000 years. I don't think it will be pretty. But, we're insanely adaptive.

I know you mean ten thousand years... but coming from the US when I first read that I interpreted it as you being VERY specific about ten years from now and not a thousanth of a year later....

That being said, probably still chasing share holder value as everything burns (hotter) around us.

But one more thousanth of a year could change that!

There will be a sedimentary layer of plastics and rare earth metals. Some more thing will have evolved to be crabs.

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.

Probably mostly dead

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.

Mars. It'll look like Mars.

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.

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.

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

Yabba-Dabba-Doo!!

Warm and stormy

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

Few AAA games.

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.

A Starbucks data center on every corner.

Cat people have taken over the world

Slightly less green.

According to Nostradamus, this world will be no more long before that. He has pointed to the year 3797 as being the final year that this Earth exists.
