Survival and procreation aren't primary goals in any direct sense. We have urges that have been selected for because they contribute to inclusive genetic fitness, but at the implementation level they don't seem to be evaluated by their contributions to some sort of unitary probability-of-survival metric; similarly, some actions that do contribute greatly to inclusive genetic fitness (like donating eggs or sperm) are quite rare in practice and go almost wholly unrewarded by our biology. Because of this architecture, we end up with situations where we sate our psychological needs at the expense of the factors that originally selected for them: witness birth control or artificial sweeteners. This is basically the same point Eliezer was making here.

It might be meaningful to treat supergoals as intentional if we were discussing an AI, since in that case there would be a unifying intent behind each fitness metric that actually gets implemented, but even in that case I'd say it's more accurate to talk about the supergoal as a property not of the AI's mind but of its implementors. Humans, of course, don't have that excuse.
