I don't completely understand why meat grown in a tube is grosser than meat cut from the bones of a dead animal. If the texture is the same, why not eat it?
Or perhaps they realize the deadly danger of cultured flesh. Just listen to "The Chicken Heart", a 1937 radio play:
I tell you that mass of flesh was a chicken heart...the tissue of which for some reason is undergoing constant, rapid, accelerating growth. With every passing hour its growth is doubling. Do you know what that means? If it is now one block in size, within thirty hours that cannibal flesh will have increased in size to one square block to the thirtieth power. VOICE RISES. In thirty hours every inch of this whole city will be crushed under that moving flesh. Within sixty hours it will have covered the entire state. Within two weeks the entire United States. You ask for the National Guard. I say call out the entire army. Blast this thing off the earth.Aaaaaaaah! Not the cannibal flesh!! Listen to the story.
