Sounds good - something very like animal proteins without raising entire animals to produce them.<p>Beyond that though, I'm really interested in foods that could be created that <i>don't</i> mimic existing foods derived from animals or plants. You could imagine a nutritionist defining requirements - combinations of proteins, fats and carbohydrates, various micronutrients. Now add the aesthetics of taste, texture, consistency etc. Some of these would be "ready to eat," either hot or cold, but others could be raw materials for traditional cooking: shred a block of this solid stuff, fry it in that liquid oily stuff, and drizzle some thick spicy stuff on it. Marketers to invent names, of course. Maybe we even get food tailored to us individually, based on specific nutritional needs, fitness goals, religious restrictions or palate.<p>This doesn't <i>sound</i> appetizing, so I think it would be a gradual process, where new products
come out that aren't <i>quite</i> like natural foods, but are still acceptably tasty, and cheaper or more nutritious. Gradually we get things that are quite different. It would take a while, but I suspect in a few hundred years we'll have things that are unimaginable today but as accepted as cheese, beer or sausage. And with much, much lower impact on the biosphere.
