Have no idea about cost. I don't have much of an ethical problem with killing and eating humanely and sustainably raised and cared for animals for a reasonable degree of those things, factory farming and assembly line slaughterhouses are not that. Better for the environment seems a no brainer given the ecological costs of the amount of meat we eat. I can't imagine it will be the same as in no difference at all, or undetectable, maybe it will even always be more delicious, but I think it's reasonable to think that for lots and lots of dishes with meat in it, it would pass a blind taste test.

Raw steak, maybe not. Beef stew or chicken curry or a burger - def...
