I agree that Siri was a lousy protagonist. He was always better at the parts where he was at home, with his girlfriend, his friend, or his family. And then in Theseus, he was the dumbest of all, always mindraped by everyone else. It's not that it had no sense, but it felt out of place.
And the quotation is, telepathically?, given by a vampire, not an alien, so it makes *barely* more sense than what it would have if Rorschach made such a point.
I loved the part of "conversation" being treated as a virus attack, and the notion that perhaps such a judgement would be quite common in the universe, as a big ***** you star trek*. Quite the self-hating treatise on how the mind is actually a perpetual senseless thing, which is utterly ironic, for it renders the whole novel as a senseless diatribe about the self, and according to itself, it passes judgement upon the novel itself as an useless virus.
It's the problem of self-contradiction, that made me irritated at the quotation in the OP, for its apparent hypocrisy. Only an ego would make such a vitriolic treatise against ego itself, and if that was made by an alien, it would have been remarkably stupid. As is, however, reads as the last remains of the ego trying to nuke itself out of existence. The whole book is. What remains? "Intelligence", it answers.
I'll have to ponder a little more about this.
