The Future of Humanity: Terraforming Mars, Interstellar Travel, Immortality, and Our Destiny Beyond by Michio Kaku

3.0

Interesting thought experiment, but I feel it goes too far. For me, half of the book was very interesting, but once it starts talking about type 3 to type 4 civilizations it is mostly guess work but shown as if it was based on science. It feels too much.
