I do not agree with all ideas brought forward by the book (esp. the bluntly exaggerated data religion), but there are some very pertinent questions raised in the last section. What shall we do when humans are made redundant by algorithms? What is going to happen when the best course to raise society's efficiency is no longer to increase the standard of living/education of humans, but becomes strictly related to computers and algorithms (i.e., you no longer have financial incentives to help humans improve themselves). Those are some bone chilling questions, but I guess it's time to start thinking about them. All in all, I would say definitely worth reading, even though the first 250 pages could be condensed quite a bit.
