Charles Stross’s Accelerando:

The lobsters are not the sleek, strongly superhuman intelligences of pre singularity mythology: They’re a dim-witted collective of huddling crustaceans. Before their discarnation, before they were uploaded one neuron at a time and injected into cyberspace, they swallowed their food whole, then chewed it in a chitin-lined stomach. This is lousy preparation for dealing with a world full of future-shocked talking anthropoids, a world where you are perpetually assailed by self-modifying spamlets that infiltrate past your firewall and emit a blizzard of cat-food animations starring various alluringly edible small animals. It’s confusing enough to the cats the ads are aimed at, never mind a crusty that’s unclear on the idea of dry land. (Although the concept of a can opener is intuitively obvious to an uploaded Panulirus.)
