GEB and Emperor's New Mind (Score 1)

I'd have to disagree. I was hoping for a good counterpoint but I felt that ENM was by far inferior to GEB. Obviously the subject they tackle is very involved and both spend a good deal of time setting up the intuitions however I found that most of ENM was irrelevant to the main point (or at least the connection was not made clear at all.) The conclusion I got from ENM was that if Penrose's oddball (by his own admission) quantum theory is correct than there is a faint possibility that the strong AI conjecture is false. Its an awful lot of book for such a weak argument.

The one point in ENM's favour is that it is the first argument I've seen against strong AI which is not directly based on circular definitions (ie definitions of intelligence which include the requirement that the subject must be human, amongst other things.) Unfortunately I don't think the case was made well.
