I’m going with either a nuclear wasteland or a world run by robots. Either way I think we will have a much smaller population, with either a significant increase in quality of life or significant decrease.
If you consider the changes over the last 100 years, what we will have 3000 years from now is unimaginable. I won’t even venture a guess.
I’ll try 100 years from now:
Robots everywhere, the breakup and demise of the USA, world totalitarianism under China. That’s plenty to think about.

It depends on if humanity expands beyond this lone plant and can occupy first other part so the solar system and then beyond.
If we can do that we will have concurred ourselves (the biggest problem) and developed technology beyond our current understanding. Earth could survive with humans. If not, it will be a post apocalyptic wasteland as far as human are concerted. Maybe we would still exist but beaten back to the stone age.

Given modern transportation and cross cultural - ah - integration. By the year 5,000 I don’t believe that there will be recognizable Asians, Indians (southern Asia), blacks, and whites.
The gene pool will be so cross pollinated by that point “ethnicity” will be a meaningless concept.

Hmm, not sure. Biologically, it seems the larger populations get the more diverse they become. Yet, like you mentioned, modern transport doesnt geographically segregate us like we used to.
The earth will always recover. It will shrug off anything we can do to it and keep rebounding like it always has, as long as the sun and its orbit around it are stable.
Why? In 100 years the USA will be 330 years old. Time for it to be gone. I can see it happening now with the extreme polarization and the rush toward socialism.
Socialism spelled the end of the British Empire and has failed everywhere it’s been tried- the USSR, Poland, Cuba, Hungary, Romania, Czechoslovakia, Yugoslavia and Valenzuela to name a few.
