Rob Rhinehart, a 24-year-old software engineer living in Atlanta, has invented the last food you'll ever need to eat. He calls it Soylent, and it's basically a very nutritious liquid meal, which is meant to be ingested the same way one might ingest actual food -- for a feeling of fullness, to provide the body with nutrients -- but without the other pesky things about food. Like, say, enjoying it, preparing it in a communal manner, chewing it. Screw that. Who do I look like, Alice Waters?
