The main reasons I’ve seen from vegans for not eating meat seem to be all about the morality of eating a sentient animal, the practices of the modern meat industry, and the environmental impact of it. And don’t have anything to do with the taste of meat.
Since lab-grown meat doesn’t cause animal suffering, and assuming mass production is environmentally friendly, would you consider going back to eating meat if it were the lab-grown kind?
I don’t think that lab-grown meat will ever replace animal agriculture on a large scale, at least in my lifetime. That being the case, I’d rather leave any ethically produced meat for people who would’ve been eating unethically produced meat instead.
If the situation is basically full on Star Trek replicator, then I wouldn’t have ethical qualms but I might still find it gross and it might not digest well since I’m not used to it. Either way, it’s very distant from the actual situation we’re in now.
