No. There are two bad assumptions in your counterexample.
They are:
Human psychopaths are above the certain point of intelligence that I was talking about.
Human psychopaths are sufficiently long-lived for the consequences to be severe enough.
Hmmmm. #2 says that I probably didn't make clear enough the importance of the length of interaction.
You also appear to have the assumption that my argument is that the AGI fears detection of its unfriendly behavior and any consequences that humanity can apply. Humanity CANNOT apply sufficient negative consequences to a sufficiently powerful AGI. The severe consequences are all missed opportunity costs which means that the AGI is thereby sub-optimal and thereby less intelligent than is possible.
What sort of opportunity costs?
The AI can simulate humans if it needs them, for a lower energy cost than keeping the human race alive.
So, why should it keep the human race alive?
[...] 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.
