Does Information Leave a Fossil?

…such was the question that popped into my head, as I was taking a stroll through my thoughts on my way to work this morning. Said popping-in was due to me thinking about what my impact would be on the world. My personal, individual impact. How long, for example, will my blogs last? With technology’s exponentially increasing capacity for information storage, will everything I ever write, every contribution I ever make to the Internet (or its future equivalent), be but the tiniest fraction of a pin-prick on the Global (and perhaps beyond) Database? And as such, will there never be any need for it to be destroyed, thus leaving it floating somewhere in the Infosphere for all time? Or will it, at some point in the future, either through some random or conscious act (and when I say “conscious,” I include the possibility of some sort of “artificial” consciousness), suffer some sort of destruction or degradation, but leave behind some kind of information “fossil,” for “techno-palaeontologists” of the future to “dig up” and ponder over the relevance of such in indicating how people of the 21st century lived? Such was the nature of this morning’s “thought-stroll”…
