If we returned to 1950s levels of meat consumption (my parents and grandparents regarded eating a chicken as a treat), or grew chickens or cows in our own backyards, maybe. But in a world of 8 billion people with our diets, cruelty, pollution, carbon impact etc are all intrinsically tied to our meat consumption.

So lab-grown, cruelty-free, without the carbon impact especially for highly polluting animals like cattle -- it's a wonderful idea.
