I get the point, but, well... Have you tried bread!? It's pretty bloody awesome and amazingly versatile! Pickled cabbage is alright, but BREAD! Come on! Discounting ethical considerations, I would 100% choose bread over meat any day.
Side note: apparently ships could keep a Galápagos tortoise unfed and unwatered in their holds for up to 6 months before they slaughtered them for food. This sounds like a truly torturous death, but from a practical view this would certainly explain why they are now endangered.
Some companies (e.g. Vow) are focusing on producing niche deluxe products that are generally unavailable to the public. Dodo is one of the animals that are considered in cultivated meat because then they won't be directly competing with the traditional meat industry.
They have already made a mammoth burger (sort of).
