Best book I've read by Stephenson in awhile. Like since Diamond Age. His early books were actual techno thrillers. As he's gotten older he seems to have settled into writing books that include a LOT more description than is absolutely necessary. This is one of those. However, for me, this one isn't as deadly as Seveneves which I gave up on. (That book's premise made it sound as if I'd love it but the pace was deadly.)

This book is set just far enough in the future that we are not there yet, but it's pretty clear that we will be. If not in the specific details, the general idea is spot on.

The characters are solid and interesting. I wanted to read about them which is what made the excess of description ok. That said, if I hadn't been stuck at home with Covid right as I started this, I might have lost the thread due to lack of time. There's a good 150 pages that could be cut right out of this book and we'd never miss it.
