I have heard stories of asteroid mining recently, but knew few detail. After reading BOLD, Peter Diamandis and Steven Kolter's thought expanding book, I understood more about its origin. Its not a big government program, it's being driven by individuals with a massively transformative purpose.
The blogs I'm interested in appear daily in my Feedly app, so I don't subscribe to emails from the many outstanding blog authors, Peter Diamandis is the one exception. BOLD expanded my thinking, as Peter might say; "exponentially."
If you're going to read only one book this year, I recommend you make it BOLD.
