Mind kinda blown.
Like much of Stephenson, the first two thirds is very well padded, even though most of it pays off later. The last third comes in a rush. I wish he were just a little better at characterization. I had to keep asking myself "wait, which one is Lio/Jesry/Arsibalt?" But overall very good, thought provoking a d definitely full of very big, very well developed ideas.
