Some books are fast reads, even if it takes a decade to start them. "Why Information Grows" by César Hidalgo is one such book. It’s a remarkable and readable exploration of how information is encoded, transmitted, and that leads to economic complexity. From the first page, he turns what could be dense theory into clear, engaging prose.

Hidalgo’s book is interdisciplinary, covering not just information theory and economics, but also blending physics, genetics, organizational theory, and more. This is accomplished by using striking analogies to make tough ideas feel familiar. He shows that economies grow with information, and networks are key to spreading knowledge. The information products of our creativity, known as “crystals of imagination”, are physical artifacts that lock in ideas so they can spread, adapt, and spark new innovations. Societies thrive when they can process and use information effectively.

Nearly ten years after its release, the book still shines. Hidalgo’s friendly, down‑to‑earth style brings complex concepts within reach.

How can someone who isn’t an economist relate to this book? For creative solopreneurs, the concept of creating "crystals of imagination" means turning ideas into something that can be shared, refined, and grown. By doing this, it’s possible harness the same forces that power entire economies, and it can turn your creative imagination into objects of lasting worth. This book offers valuable insights into how information and creativity drive economic growth, making it a must-read for anyone interested in understanding the dynamics of modern economies.
