Caledonian, let me guess: you didn’t actually finish Permutation City.
I’ve read that FAQ before, and I’m aware of the objections you refer to. The quick response is that Egan doesn’t fully understand the restrictions inherent to what he speculated about.
Borges had a better understanding. Not anywhere near Egan’s grasp of mathematics, of course—but the argument isn’t being made in mathematics. I suspect this is a large part of the problem, since some of you keep making an invalid argument.
