Human evaluation of human values under specific instances is everything that Ben says it is (complex, nebulous, fuzzy, ever-shifting, and grokked by implicit rather than explicit knowledge).
On the other-hand, evaluation of a points in the Mandelbroit set by a deterministically moving entity that is susceptible to color-illusions is even more complex, nebulous, fuzzy, and ever-shifting to the extent that it probably can't be grokked at all. Yet, it is generated from two very simple formulae (the second being the deterministic movement of the entity).
Eliezer has provided absolutely NO rational arguments (much less proof) that the core of Friendly is complex at all. Further, paying attention to the fact that ethical mandates within the obviously complex real world (particularly when viewed through the biased eyes and fallible beings) are comprehensible at all would seem an indication that maybe there are just a small number of simple laws underlying them (or maybe only one -- see my comment on Ben's post cross-posted at http://becominggaia.wordpress.com/2010/10/30/ben-goertzel-the-singularity-institutes-scary-idea/ for easy access).
My take on the optimisation target of all self-organising systems:
http://originoflife.net/gods_utility_function/
Eliezer Yudkowsky explains why he doesn't like such things:
[...] SIAI's Scary Idea goes way beyond the mere statement that there are risks as well as benefits associated with advanced AGI, and that AGI is a potential existential risk.
[...] Although an intense interest in rationalism is one of the hallmarks of the SIAI community, still I have not yet seen a clear logical argument for the Scary Idea laid out anywhere. (If I'm wrong, please send me the link, and I'll revise this post accordingly. Be aware that I've already at least skimmed everything Eliezer Yudkowsky has written on related topics.)
So if one wants a clear argument for the Scary Idea, one basically has to construct it oneself.
[...] If you put the above points all together, you come up with a heuristic argument for the Scary Idea. Roughly, the argument goes something like: If someone builds an advanced AGI without a provably Friendly architecture, probably it will have a hard takeoff, and then probably this will lead to a superhuman AGI system with an architecture drawn from the vast majority of mind-architectures that are not sufficiently harmonious with the complex, fragile human value system to make humans happy and keep humans around.
The line of argument makes sense, if you accept the premises.
But, I don't.
