What would you consider synthetically produced 'meat' that wasn't part of an animal? Are there any other salient variables for classification which come to mind? In my opinion, structured growth of 'muscle tissue' disconnected from any animal is still "fake meat". Unfortunately, as far as I'm aware, it is either still science fiction or too expensive (otherwise I'd have heard about it from places that aren't scifi).
