I am also to some extent skeptical but I can recreate some of the arguments for the possibility of AI-caused explosive change that I've heard.
We certainly take the concept of intelligence and intellectual power seriously when we deal with other humans (e.g. employers evaluating potential hires, or in diagnosing mental retardation). To some extent, we expect that a human with computational tools (abacus, pen and paper, calculator, computer) will have increased intellectual capabilities - so we do judge the power of "cyborg" human-computer amalgams.
We have explosive change today - if "explosive" intended to mean the type of exponential growth process exhibited in nuclear bombs. Check with Moore's law.
If you are looking for an explosion, there is no need for a crystal ball - simply look around you.
Robin criticizes Eliezer for not having written up his arguments about the Singularity in a standard style and submitted them for publication. Others, too, make the same complaint: the arguments involved are covered over such a huge mountain of posts that it's impossible for most outsiders to seriously evaluate them. This is a problem for both those who'd want to critique the concept, and for those who tentatively agree and would want to learn more about it.
Since it appears (do correct me if I'm wrong!) that Eliezer doesn't currently consider it worth the time and effort to do this, why not enlist the LW community in summarizing his arguments the best we can and submit them somewhere once we're done? Minds and Machines will be having a special issue on transhumanism, cognitive enhancement and AI, with a deadline for submission in January; that seems like a good opportunity for the paper. Their call for papers is asking for submissions that are around 4000 to 12 000 words.
The paper should probably
Devote the second half to discussing the question of FAI, with references to e.g. Joshua Greene's thesis and other relevant sources for establishing this argument.Carl Shulman says SIAI is already working on a separate paper on this, so it'd be better for us to concentrate merely on the FOOM aspect.I have created a wiki page for the draft version of the paper. Anyone's free to edit.
