I'm optimistic that we'll be around in 8k years, but less so that anything written now will survive regardless of how we record timestamps. Posts regularly come up here of sites shuttering with little to no notice and we're increasingly seeing a migration to app walled gardens which are actively hostile towards open standards and by extension archiving. The ancients were on the right track carving their histories into stone.
I'm even more optimistic; the Sumerian language is now 5000 years old we can read that. I used to love stone runes but after reading Snow Crash clay tablets that the sumerians used seems to be the best path, it's so much faster and practical. A bit like the internet vs. floppies.
