Heh. I've read virtually all those links. I still have the three following problems.
What I asked for was "an immediately available well-structured top-down argument".
It would be particularly useful and effective if SIAI recruited someone with the opposite point of view to co-develop a counter-argument thread and let the two revolve around each other and solve some of these issues (or, at least, highlight the base important differences in opinion that prevent them from solution). I'm more than willing to spend a ridiculous amount of time on such a task and I'm sure that Ben would be more than willing to devote any time that he can tear away from his busy schedule.
There are some fundamentally incorrect assumptions that have become gospel.
So go ahead and point them out. My guess is that in the ensuing debate it will be found that 1/4 of them are indeed fundamentally incorrect assumptions, 1/4 of them are arguably correct, and 1/2 of them are not really "assumptions that have become gospel". But until you provide your list, there is no way to know.
[...] 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.
