Kindle Notes & Highlights
“Replicator networks,” Jason said, “are one of the things sentient civilizations tend to produce. Given the inherent difficulty of sublight-speed travel as a way of exploring the galaxy, most technological cultures eventually settle for an expanding grid of von Neumann machines—which is what the replicators are—that costs nothing to maintain and generates a trickle of scientific information that expands exponentially over historical time.”
Ars moriendi ars vivendi est: the art of dying is the art of living. I had read that somewhere in my postgraduate days and remembered it as I sat at his side. Jason died as he had lived, in the heroic pursuit of understanding. His gift to the world would be the fruits of that understanding, not hoarded but freely distributed.
The world is full of surprises. We’re all born strangers to ourselves and each other, and we’re seldom formally introduced.”
When people come to understand how big the universe is and how short a human life is, their hearts cry out. Sometimes it’s a shout of joy: I think that’s what it was for Jason; I think that’s what I didn’t understand about him. He had the gift of awe. But for most of us it’s a cry of terror. The terror of extinction, the terror of meaninglessness. Our hearts cry out. Maybe to God, or maybe just to break the silence.”
