If we’re talking about whether top down meat is viable or not we don’t need to appeal to all vegetarians and vegans. The question isn’t, “if you gave a brainless chicken meat to a random vegetarian right now would they eat it?” The question is, “if you developed brainless chicken meat could you, with a few years of marketing, and some startup money, get a customer base to eat it and consistently buy it?”
I think the actual question is somewhere intermediate between those two. (Developers of brainless chickens might not be willing to wait a few years before seeing sales; supermarkets might not be willing to adopt brainless chicken meat widely before seeing evidence that plenty of people would buy it; etc.)
But I think the answer even to your second question is no, for the same reasons I already gave; I don’t think those things will change easily.
