Stephenson has done some great things, but dude needs an editor badly. I'm afraid success has scared off anyone who can tell him when to stop.

Fall, had some interesting and vivid passages, but the whole "Dodge wakes up in a simulation with a brain injury" bit, and really the rest of the book from there to the end could have been cut. That would leave us with a much better 350 page novel about the near future instead of yet another Stephenson -- much longer than the original! -- attempt at retelling the Book of Genesis.
