SIAI, Yudkowsky, Friendly AI, CEV, and Morality
This post entitled A Dangerous "Friend" Indeed (http://becominggaia.wordpress.com/2010/06/10/a-dangerous-friend-indeed/) has it all.
Huh. That's very interesting. I'm a bit confused by the claim that evolution bridges the is/ought divide which seems more like conflating different meanings of words more than anything else. But the general point seems strong.
Yeah, I really disagree with this:
My understanding is that those of us who refer to the is/ought divide aren't saying that a science of how humans feel about what humans call morality is impossible. It is possible, but it's not the same thing as a science of objective good and bad. The is/ought divide is about whether one can derive moral 'truths' (oughts) from facts (ises), not about whether you can develop a good model of what people feel are moral truths. We'll be able to do the latter with advances in technology, but no one can do the former without begging the question by slipping in an implicit moral basis through the back door. In this case I think the author of that blog post did that by assuming that fitness-enhancing moral intuitions are The Good And True ones.
Dig a bit deeper, and you'll find too much confusion to hold any argument alive, no matter what the conclusion is supposed to be, correct or not. For that matter, what do you think is the "general point", and can you reach the point of agreement with Mark on what that is, being reasonably sure you both mean the same thing?
