MySpace was much earlier, as well as a few other forerunners

We are a tiny slice of history. A thousand years from now we may be hazily recalled as the period that slavery was abolished (edit: sadly enough we probably won't be) , electricity and computers were invented, 3 of the world wars occured, and the first great population explosion and cultural implosion took place. Most electronic information will be lost so our century will be known as the electronic dark ages. All of this will be studied by the advanced artificial intelligence entities and the sentient cockroaches, the last surviving carbon life forms on earth.

3 world wars?
