I actually hope this really takes off. Even PETA (whom I really disagree with on most things..) offered a million to the first company that did this, cause that would end the need to actually kill animals to supply people with protein rich meats. If people could grow steak like carrots, why wouldn't they?? I'm no vegan, but I don't eat baby animals or food that needs animals to be tortured (IE: Fragra), but we are carnivores by nature.
After all, if some alien race came down, and said "look, we are going to start eating you guys, but you have the choice to either live a full life, we will provide you with food and things will be good, but when you turn 60, your OUR food, or, we treat you like crap and kill you whenever, or you live in the wild, no tech, and likely die of disease or from other animals killing you so they don't starve before you even reach 20." I think most the world would be asking "where do I sign up for the first option".
As long as it tastes like meat when cooked, and gives the same nutrients, then heck yeah I'd eat it over causing harm to other sentient animals.
