In Tomorrowland, author Steven Kotler describes fundamental advances in science that have changed and will continue to change our world. Essentially, Kotler is writing about science fiction becoming science fact, which is happening at a remarkable rate. For example, he talks about such futuristic ideas as mining asteroids, biological warfare, and advanced prosthesis. I found the book entertaining but not much more than that. I picked it up for free when I tried out Kindle Unlimited. Otherwise, I probably wouldn’t pay for it.
