Humans and Babykillers are not talking about the same subject matter when they debate what-to-do-next, and their doing different things does not constitute disagreement.
We talk about what is good, and Babykillers talk about what is eat-babies, but both good and eat-babies perform analogous functions. For building a Friendly-AI we may not give a damn about how to categorize such analogous functions, but I've got a feeling that simply hijacking the word "moral" to suddenly not apply to such similar things, as I think it is usually used, you've successfully increased my confusion through the last year. Either this, or I'm back at square one. Probably the latter.
In You Provably Can't Trust Yourself, Eliezer tried to figured out why his audience didn't understand his meta-ethics sequence even after they had followed him through philosophy of language and quantum physics. Meta-ethics is my specialty, and I can't figure out what Eliezer's meta-ethical position is. And at least at this point, professionals like Robin Hanson and Toby Ord couldn't figure it out, either.
Part of the problem is that because Eliezer has gotten little value from professional philosophy, he writes about morality in a highly idiosyncratic way, using terms that would require reading hundreds of posts to understand. I might understand Eliezer's meta-ethics better if he would just cough up his positions on standard meta-ethical debates like cognitivism, motivation, the sources of normativity, moral epistemology, and so on. Nick Beckstead recently told me he thinks Eliezer's meta-ethical views are similar to those of Michael Smith, but I'm not seeing it.
If you think you can help me (and others) understand Eliezer's meta-ethical theory, please leave a comment!
Update: This comment by Richard Chappell made sense of Eliezer's meta-ethics for me.
