I never meant to impugn the man or his character and I now regret invoking schizophrenia so casually. As you said, his case isn't well put. It is his writing and arguments which I find sloppy and the connections he makes, as presented, smell somewhat delusional. This is not the same as saying that he's "crazy".

I am rejecting, strongly, the assertion that his is a principled stance. The piece is simply is not compelling since his malicious AI would be acting on behalf or under the command of humans, just like all weapons throughout history. I think it's a simplistic, misguided, stance. The kind I remember flirting with when I first took some college-level philosophy courses years ago.
