I would have never imagined that a book about the utter obliteration of the world could be so hopeful.

I recently read D.O.D.O., and I'm convinced that it's in the same literary world as Anathem and Seveneves. I won't say more, but do read D.O.D.O., if you've otherwise liked Stephenson's work.

Indeed. I'd say more, but spoilers.

I'm a licensed HAM radio operator, but I'm too young to have gone through the Morse era. One of the things that book did for me was kindling my interest in learning to transmit and receive Morse.

I mean, you never know when you might need it, right? :)

I'm a Ham too and I'm wondering if it might be a good time to assemble a crystal radio - no power needed.

my first thought as well
