the manual might be closer to 900,000 pages Knowing a thing or two about neurophysiology, this seems like a vast underestimation (since a biology book should also cover that, likely most complicated of all, topic). So vast I wouldn't even dare putting a number on it, because there is so much we don't know about the brain, it is hard to even estimate how much we don't know. (Which by the way also puts some AI claims regarding replication of brain functionality in a different light)
