The twist of Blindsight is that a fundamental assumption about the nature of intelligence is false. The book takes a very long time setting this up and then it hammers it into both the reader and the protagonist. It seems to be saying, "Hey this is a big deal and you're not going to accept it, so I'm going to shovel it down your throat with a snow plow." In Echopraxia they have the same idea, but it's trivialized in a blink and you miss it throwaway line and accepted as fact by everyone. I get that the author didn't want to just retread the same ground over and over. However, I feel it's a mistake to trivialize something that a bunch of post human super savants were surprised by.
