So...it's a proof, and it hasn't been contradicted, and yet, it's "viewed with suspician"....sounds more like a blundering-around science than a pellucid palace of logic to me.
A proof is something that can convince a reasonable and knowledgable person. It is the highest hurdle in academia, but it still has its fuzziness. Suffice it to say that I was not convinced by A&H. It's a moot point now.
