A Gödel machine, if one were to exist, surely wouldn't do something so blatantly stupid as posting to the Internet a "recipe for practically feasible self-improving Gödel machines or AIs in form of code into which one can plug arbitrary utility functions". Why can't humanity aspire to this rather minimal standard of intelligence and rationality?
Similar theme from Hutter's paper:
Will AIXI replicate itself or procreate? Likely yes, if AIXI believes that clones or descendants are useful for its own goals.
If AIXI had the option of creating an AIXI (which by definition has the goal of maximizing its own rewards), or creating a different AI (non-AIXI) that had the goal of serving the goals of its creator instead, surely it would choose the latter option. If AIXI is the pinnacle of intelligence (as Hutter claims), and an AIXI wouldn't build another AIXI, why should we? Because we're just too dumb?
...has finally been published.

The issue consists of responses to Chalmers (2010). Future volumes will contain additional articles from Shulman & Bostrom, Igor Aleksander, Richard Brown, Ray Kurzweil, Pamela McCorduck, Chris Nunn, Arkady Plotnitsky, Jesse Prinz, Susan Schneider, Murray Shanahan, Burt Voorhees, and a response from Chalmers.
McDermott's chapter should be supplemented with this, which he says he didn't have space for in his JCS article.
