My work was recently cited by Remi Sussan at the Greek online journal Re-public, in an article "Transhumanism and Hermetism". The relevant passage says:
Are there any cybermarcionists? We watch them being erased in various currents about "singularity" who suspect that the real birth of transhumanity will occur with the creation of an intelligence, superior to the human being. This superior intelligence could be a mutant human being but for some, the human brain is structurally too defective to allow the passage to a superior level. Only an artificial intelligence, maximized from the beginning, can allow this "singularity".
The citation, , refers to a footnote that says, "See, for example, Michael Anissimov, Forecasting Superintelligence: the Technological Singularity. I want to point out that nowhere in my article do I say that "the human brain is structurally too defective to allow the passage to a superior level." That claim is completely false. I only say that it seems likely that AI will cross the line into superintelligence before intelligence amplification (IA) does, for various reasons that are listed in the article. I absolutely do think that the structure of the human brain is amenable to intelligence enhancement, but it seems like enhancing the incredibly complex biological brain is a difficult challenge that would be most easily and safely approached with the assistance of strong AI.
I would further like to add that I believe there is a very strong bias that leads people to exaggerate the potential of IA over AI in their minds, because IA is 1) more personal, 2) has greater positive affect, 3) is more easily imaginable, 4) more flattering to humanity, and 5) featured more heavily in science fiction, to name a few reasons. I consider it possible that IA will lead to superintelligence before AI, and I am in favor of ethically cautious IA research, but it seems (to me, anyway) like seed AI is more likely to lead to strong superintelligence before any IA technologies.
Let me also point out, though, that there may be people in favor of IA over AI that have successfully sidestepped the above biases. Such people should feel free to share their arguments.
