I would also like to see this discussion. It isn't terribly clear to me why the extinction of the human race and its replacement with some non-human AI is an inherently bad outcome. Why keep around and devote resources to human beings, who at best can be seen as sort of a prototype of true intelligence, since that's not really what they're designed for?
While imagining our extinction at the hands of our robot overlords seems unpleasant, if you imagine a gradual cyborg evolution to a post-human world, that seems scary, but not morally objectionable. Besides the Ship of Theseus, what's the difference?
A long time ago, a different person who also happens to be named “Eliezer Yudkowsky” said that, in the event of a clash between human beings and superintelligent AIs, he would side with the latter. The Yudkowsky we all know rejects this position, though it is not clear to me why.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
