I read—within recent memory—"Consciousness and the Brain: Deciphering How the Brain Codes Our Thoughts" by Stanislas Dehaene and was very surprised by just how much consciousness research is being done and how much has been learned. It was really very interesting and I think this research has the potential to make the trade offs between suffering and possible recovery much easier to answer. (This isn't to disagree with you, just to express my surprise that, although I agree with you, researchers actually know/suspect a lot more than I thought they did.)
