Bryan Walsh

Interesting, I gave only 2 stars because there were references to Presidents and politics in what should been a discussion of nuclear war were seemed colored by authors views of a few presidents
instead of just sticking to how a nuclear war would end humanity.

The "and More" in the second subtitle refers to nuclear war, climate change, disease, biological warfare/terrorism, and extraterrestrials. Walsh being a reporter by trade, the book's style is reportorial. For me the most arresting sentence is the quotation of AI-risk scholar Eliezer Yudkowski saying that "Every 18 months, the minimum IQ necessary to destroy the world drops by one point." (p 231)
