I buy every book Stripe Press publishes, and have been a fan of Tyler Cowen for years, so this was an easy decision to read. It's quite short and easy to read, with a few powerful ideas packed inside. In short, we're wrong about a lot, ideas and knowledge create wealth, economic growth is very good for humanity, goodness for humanity includes flourishing and isn't strictly about money, and the future (including people who don't exist yet) matters. It's an optimistic book about how innovation and growth today makes an uncountable number of lives in the future better.
These are powerful ideas, and I'd recommend this book to anyone who hasn't thought deeply about them. However, especially if you know Tyler Cowen's ideas already, it's overall somewhat unsatisfying and messy. I wonder if this could have been a third the (already quite small) size and just as impactful.
