Another old economist. You don’t hear about Galbrath much anymore.

I read this book in 2001 after it was named a finalist for best 2000 Visionary Fiction. I liked the premise & kept it for 25 years.
Recent speculation about 3I/Atlas’ comet/aliens & physics theories of consciousness reminded me of the story. Precognition? I don’t know, but I enjoyed rereading it.
