I read most of the thread here but not all, so I hope I'm not repeating anything yet said: I'm convinced that once we can produce meat rather than butchering animals, why in the world would anybody want to farm animals? I guess cows and pigs would be the next animals going to be extinct soon.
So I doubt it's that a good idea to be able to produce meat.
Well, let's see.... perhaps the farmed animals taste better, perhaps some people enjoy the connection with the land and Nature by growing/raising their own food, animals aren't just raised for meat: many animals (sheep, goats, etc) are also raised because their wool/hair can be used for clothing, cows provide leather, beef shanks probably aren't going to be grown in a lab, but a slowly braised shank of beef is absolutely divine!
Put a simpler way: you can buy cheap beef at the grocery store, but the bison farm down the road from me that sells grass-fed, pastured bison meat still has a 4-6 month backlog on orders...
So I doubt it's that a good idea to be able to produce meat.
