The book was effectively a long catalog of many of the exciting technologies people have recently launched or are actively working towards across many fields such as robotics and medicine. It was nice from the one hand to hear about the many big problems facing the world and the different initiatives people are taking to fix them. But I found the book to be too descriptive of the current solutions and approaches, and so I think it will be quite dated in a few years. I would have preferred more detail on the actual problems because those are the entry points to real opportunities.
Even though I expected a bit more depth to the various arguments and less cataloging of examples, it was still an interesting read.
