If lab-grown meat becomes even half as good (and cheap) as slaughtered meat then I'd make the switch in a heartbeat. Not to mention, imagine being able to try out all sorts of exotic meats guilt-free, or being able to eat raw meat without risk of food-borne illness and parasites? Gimme some of that cruelty-free giant tortoise meat, lemme see what that gluttonous bitch Charles Darwin was on about.
Plant based meats have been way more than half as good for a while (iirc some of them have even won blind tests), I don't get why people are so obsessed with lab grown versions.
But also, liking how someone tastes isn't a good justification for killing them, regardless of how good or bad the alternatives are. Fortunately there are tons of delicious vegan foods so it's a moot point
