How expensive is making humans vs. their utility?
Utility for what purpose? If we're talking about say, a paperclip maximizer, then its utility for human beings will be measured in paperclip production.
Is there something markedly more efficient that won't complain or rebel if you treat it poorly? How efficient/useful could a human be if you treated it well?
It won't be as efficient as specialized paperclip-production machines will, for the production of paperclips.
Are you willing to accept that premise and see if you can draw any helpful conclusions or give any helpful advice?
Yes, but you're unlikely to be happy with it: read the sequences, or at least the parts of them that deal with reasoning, the use of words, and inferential distances. (For now at least, you can skip the quantum mechanics, AI, and Fun Theory parts.)
At minimum, this will help you understand LW's standards for basic reasoning, and how much higher a bar they are than what constitutes "reasoning" pretty much anywhere else.
If you're reasoning as well as you say, then the material will be a breeze, and you'll be able to make your arguments in terms that the rest of us can understand. Or, if you're not, then you'll probably learn that along the way.
[...] 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.
