"The retina is about two centimeters wide and a half a millimeter thick. Most of the retina's depth is devoted to capturing and image, but one fifth of it is devoted to image processing, which includes distinguishing dark and light, and detecting motion in about one million small regions of the image.
"The retina, according to Moravec's analysis, performs ten million of these edge and motion detections each second. Based on his several decades of experience in creating robotic vision systems, he estimates that the execution of about one hundred computer instructions is required to re-create each such detection at human levels of performance, meaning that replicating the image-processing functionality of this portion of the retina requires 1,000 MIPS."

Yeah, I'm just about to start the book (it's been on the floor for over 6 months, and the whole purpose of this vacation was to catch up on books, movies, and photos), but I can already tell it's going to be a bit "out there."

actually, I think he may have made the exact point in Spiritual Machines, almost word-for-word. I'd have to check, but I got freaky deja-vu.
Either that, or his writing style has just sort of melted all the content from the book inside my head, so that everything he writes sounds the same. >80
