Miss Mango makes a good point - what about the bones? Is my T-Bone steak now going to be bonelss? Will 'rump' and 'sirloin' taste the same? Will the saying 'sucking the marrow out of life' become a distant memory?
At first glance it looks like a good idea but I'm worried about the economic impact of it all. If you can produce a whole cow's worth of meat faster and cheaper than my buddy who has a farm and a coupla dozen employees...well, sucks to be them. On the flipside we have the world hunger issue and it's possible benefits there.
I'll hold off on the fake meat until its been thoroughly tested and all of that. Who knows, maybe real cow will become some kind of a delicacy in the next 10-15 years.
