We are most likely stuck with factory farms, given that they produce most of the beef and pork Americans consume. But it is still possible to reduce the animals’ discomfort — through neuroscience. Recent advances suggest it may soon be possible to genetically engineer livestock so that they suffer much less.

I find this extremely disturbing -- that educated people, the leaders of society, would devote time to genetically warping animals to not feel pain to support the gluttony of humanity.
