Oh a LOT will still be around in ten thousand years, especially if climate change causes a lot of desertification. The oldest Egyptian papyrus is almost 4,600 years old and that’s just papyrus, an organic material that doesn’t survives very long in more humid climates.

Ten thousand years isn’t very much in geological timescales, not enough to bury everything and crush it to dust so anything that gets left in a landfill (and not harvested in the future) has a chance of surviving. Anything made of noble metals like gold and platinum especially, so it’ll mostly be a question of how much is thrown away versus recycled.

Our modern middens will be full of artifacts.

There are definitely projects designed with the specific intent of doing that, e.g. https://longnow.org/clock/

But there are other things, including awesome-and-dangerous nuclear waste sites, with warning messages/symbols designed to last beyond the collapse of modern civilization https://en.wikipedia.org/wiki/Long-term_nuclear_waste_warnin...

The Disney copyrights will still be around.

You can leave your own kiln fired clay tablet. https://dumbcuneiform.com

Our geostationary satellites should probably be able to last for a billion years without major decay.
