You sit at the edge of the ocean, wherever the coast will be after Miami is abandoned to the waves. You are thirsty. Random little clots of dust are full-on robotic interactive devices, since advertising companies long ago released plagues of smart dust upon the world. That means you can always speak and some machine will be listening. “I’m thirsty, I need water.” The seagull responds, “You are not rated as enough of a commercial prospect for any of our sponsors to pay for freshwater for you.” You say, “But I have a penny.” “Water costs two pennies.” “There’s an ocean three feet away. Just desalinate some water!” “Desalinization is licensed to water carriers. You need to subscribe. However, you can enjoy free access to any movie ever made, or pornography, or a simulation of a deceased family member for you to interact with as you die from dehydration. Your social networks will be automatically updated with the news of your death.” And finally, “Don’t you want to play that last penny at the casino that just repaired your heart? You might win big and be able to enjoy it.»
