This book should be read, both as it is one of the few books with a 100-years perspective, but perhaps even more as it demonstrates that it does not always help to ask for a long-term perspective. If people are incapable of adopting such a perspective the outcome will not be as good as the idea. The idea behind the books is great and Ignacio frames to book in a very interesting way.
Still almost all the contributions are extremely boring. The first boring contributions inspired me as I tried to understand why they did not do anything interesting with the opportunity given to them by Ignacio, but after a few chapters it became slightly depressing reading text after text from reasonable intelligent people who obviously had no interest in a long-term perspective. Many of the contributors spent a lot of time discussing why it was hard/difficult to adopt a long-term perspective.
I had to include it in my 22nd-century-voices list (those who look beyond 2100), but it was not obvious as I would have hoped.
As Ignacio approach and focus is better than this book, I will keep my fingers crossed for another book. Perhaps nothing more is needed than time, so that this fresh perspective will be more accepted and that the contributors will have more time to reflect on a 100 years perspective.
