Okay, you've grown meat in a test tube, but who's going to eat it? The whole point of real meat is the flavor that's imparted to it through its feed and husbandry. There's a reason why some people raise and slaughter their own cattle, or grind their own meat, or buy the frozen patties from the warehouse club store.
This whole thing is like a Concept Car: Sure, it can be done; sure, it's as expensive as hell; sure, it can be eaten; but who in their right mind is going to eat it? I have a feeling this is going to be Post's "Blinky Moment", where the 3-eyed fish is cooked and served, but whether it's edible or not is a whole different story.
