Chapter 1: Owls and Ostriches
Chapter 1 establishes the pros and cons of keeping your head in the sand, ignoring what's going outside of Java. It argues that when a language is in its prime, this is perfectly appropriate, even beneficial, as it's better to spend your time with the language du jour than to look for alternatives. But when a language starts to show signs of wear, it's time to start looking for alternatives. Is it time? The chapter uses the analogy of boiling a frog, which doesn't even realize it's boiling until it's too late.
