I'm afraid I don't remember which post he discusses the idea that scientists should worry about the ethics of their work, and I'm having a difficult time finding it. If you want to find that specific post, it might be better to create an open request in a more prominent place and see if anyone else remembers which one it was.

Although it would take a much longer time though, I think it might be a good idea for you to read all the sequences. Eliezer wrote them to bring people up to speed with his position on the development of AI and rationality after all, so that if we are going to continue to have disagreements, at least they can be more meaningful and substantive disagreements, with all of us on the same page. It sounds very much to me like you're pattern matching Eliezer's writing and responding to what you expect him to think, but if his position were such a short hop of inferential distance for most readers, he wouldn't have needed to go to all the work of creating the sequences in the first place.
