An interesting and at times difficult read. As someone with an inadequate scientific education, I was able to understand and follow his narrative - perhaps not as critically as it requires - but I wasn’t drowning in jargon. He writes sensibly enough. It’s an interesting thought experiment and I spent swaths of the book imaging the world he presented. Some of it glorious but most of it depressing (Houston, Texas: land of my birth and upbringing most of all! The Great Pacific Garbage Patch! American imperialism, too). There’s a small, hopeful(?!) snippet - pp 239-40 - claiming coronaviruses won’t kill us all nor is it worth the trouble to weaponize them! Yay? Most interesting to me is the notion that the one human artifact that will live on the longest is radio waves sent into space...
