[...] 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.

There are no correct answers in a dispute about definitions, only aesthetic judgments and sometimes considerations of the danger of hidden implicit inferences. You can't use authority in such an argument, unless of course you appeal to common usage.
However, referring to a book without giving an annotation for why it's relevant is definitely an incorrect way to argue (even if a convincing argument is contained therein).
Disputes about the definition of "evolution"? I don't think there are too many of those. Mark Ridley is the main one that springs to mind, but his definition is pretty crazy, IMHO.
Why the book is relevant appears to be already being made pretty explicit in the subtitle: "An Evolutionary Account of the Social and Conceptual Development of Science".
