You could grow a steak the size of a small truck, presumably.
I’ve got my doubts as to whether people will find the above-linked method of meat production acceptable. Cloning livestock seems to make people skittish, much less meat-from-a-vat. Of course, growing it in a vat would likely take up a lot less water and grain and land resources than our current method of raising livestock for meat.
I wonder if we would be able to grow it in specialty shapes? You know, send in a picture or two, and then get a pork chop with your profile, or in the shape of the Statue of Liberty (the latter being handy for Fourth of July cookouts).
On the other hand, if it goes into production without much fanfare, maybe no one will care. Folks in the U.S. have been eating GMO crops for years with little in the way of substantial protest. People in the E.U., and particularly the U.K., have been much more vigorous in their opposition to GMO crops, particularly grain (which ends up in lots of other products).
In the U.S., it seems that GMO has been opposed mainly by the foodie crowd, with some support from the “we protest everything” crowd. (Anyone remember Starlink? Anyone?)
So, maybe I’m just way off on this, and people will have no problem with meat-from-a-vat. I guess milk from clones may be the first real test, but I still find it all a bit creepy.
