Yes, I've had this thought: that this is the beginning of the "high density" version of recorded history.

That, barring a cataclysmic implosion of civilization, the internet archives being populated now will likely be available for perusal 10,000 years from now.

As a corollary thought, an interesting exercise might be to only generate content -- movies, essays, fiction, non-fiction, whatever -- that you think people 10,000 years from now will find interesting. How does this constrain what projects to undertake?
