This is life now. You eat a slice of cake and maybe you enjoy it. An algorithm somewhere observes this and serves you another slice of cake. I like cake, you think, and you eat the second slice. It goes on like this for a long time - the cakes getting bigger, the frosting ever more elaborate. After a while you start to feel sick, but all you’ve ever known is eating cake, and anyway this restaurant doesn’t seem to serve anything else.
