Book reviews and notes

• ★★★★★ The Intelligence Illusion: a practical guide to the business risks of Generative AI by Baldur Bjarnason Mar 9, 2025 At the time I’m writing, this is the best book you can read to form an opinion around the “dysfunctions, risks, and flaws of generative models” that very rarely reach the mainstream. Read book notes.

• ★★★★☆ Rebooting AI by Gary F. Marcus, Ernest Davis Sep 18, 2024 The book accurately describes the problems with the current trend of AI development, problems from which large language models and tools like ChatGPT greatly suffer. Only the book was written before ChatGPT! It’s impressive how actual the book can be, and even more impressive is learning how these problems have been known for years now and the industry seems to just not care. Read book notes.

• ★★★★☆ Elon Musk by W. Isaacson Feb 15, 2024 Great read as any biography from Walter Isaacson, it’s a massive volume but it was very enjoyable and fast to read. Love him or hate him, Musk is a very influential individual for our time, and the book unveiled for me several details about the events that made him “Elon”. I really appreciated the details around his working philosophy: the urgency, his “engineering first” attitude, his morbid attraction for problems that seem impossible to solve. Read book notes.

• ★★☆☆☆ What You Do Is Who You Are: How to Create Your Business Culture by B. Horoviz Jul 15, 2023 I can’t recall another time when reading a book made me uncomfortable. The book is supposed to teach you how to set up a strong culture in your company but to do so it uses examples from: a controversial military leader, a feudal system well known for its rigid hierarchies, a perpetrator of multiple genocides and last but not least, a prison gang leader. I kinda see the idea behind the book, but the execution is terrible, peaking with the cringey quotes from rap songs at the beginning of each chapter. The book contains great stories and good insights but you have to dig, not sure it was worth it. Read book notes.

• ★★★★★ Atlas of AI by K. Crawford Jul 10, 2023 This book is a masterpiece: the metaphor of the atlas, the many thorough notes, the data behind each chapter is just amazing. The author also shows fine technical skills that let her jump from politics to hardware and algorithms flawlessly as the narrative requires. This book is an eye-opener for those who think about modern AI as “software”, whereas the environmental and human costs are massive. Read book notes.
