All of Tim Tyler's points have been addressed in previous posts. Likewise the idea that evolution would have more shaping influence than a simple binary filter on utility functions. Don't particularly feel like going over these points again; other commenters are welcome to do so.

Or perhaps someone else will at least explain what "having more shaping influence than a simple binary filter on utility functions" means. It sounds like it's supposed to mean that all evolution can do is eliminate some utility functions. If that's what it means, I don't see how it's relevant.
