[...] 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.

Eliezer figures out how to download his own brain. The emulation requires only a small amount of processing speed and memory. With the financial backing of the SIAI, LessWrong readers and wealthy tech businesspeople we create millions of Ems and have each run at 1,000 times the speed that Eliezer runs at. All of the Eliezer ems immediately work on improving the Ems' code and make huge use of trial and error in which they make some changes to the code of a subset of the Ems and give them intelligence tests, throwout the less intelligent Ems and make many copies of the superior ones.
This could give us a singularity in a week.
Your scenario strikes me as laughably overoptimistic. A brain emulation requires only a small amount of processing speed and memory? A story that begins with finding financial backing takes only a week to reach completion?
But in any case, this is a closed-loop recursive self-improvement FOOM. I don't doubt that such things are possible. My point was that if you already have a bunch of super-Eliezers, why not have them design a provably-correct FAI, rather than sending them off to FOOM into an uFAI? If they discover the secret of FAI within a year or so, great! If it turns out that provably correct FAI is just a pipe-dream, then maybe we ought to reconsider our plans to close the loop and FOOM.
