My perspective is that even though current meat production is quite efficient, from the fundamental physics there’s no way that growing a whole living being with a brain and bones and all that is the most efficient possible way of producing this (and immune systems are irrelevant if you have good enough isolation). I do agree that at our current tech level it seems like synthetic meat won’t be competitive anytime soon. While vegan alternatives are delicious to many people, it’s not exactly the same (though wanting to eat animals for psychological reasons is definitely part of it). Though I do agree that these issues are uncertain!
