Intrigued by the title, I sought this book out to learn more about Claude Shannon and how he lived his life. In the end, I think the title was a bit of misleading: curiosity was Shannon's driver more than play.
I can strongly relate to Shannon in this; while I may not be the genius pioneer of a new field, I believe strongly that curiosity and creative play (or tinkering as Shannon did) are truly enriching. And if you keep figuring out how things work and exploring ideas that you find interesting, then eventually one of them may truly be groundbreaking. It's not about ambition or fame or awards. It's about following your interests wherever they may lead.
In any case, the book itself was very approachable and I would recommend it to anybody who might be interested in the history of Information Theory.
