2.5 stars rounded up. Such a strange and discombobulated book. I listened to the audiobook over several days and depending on which part I started playing after a listening break, I felt like this at times a popular science book, a business and innovations book, a technical science textbook, a philosophy book, a half-baked linguistics book, or several of those at once. I enjoyed the technical science components most (given that that's my background -- I think about duplicated genes a lot in my work as I have to infer a genetic mutation's interpretation often from homologous genes/proteins). However, I felt that other parts of the book might have been written by ChatGPT run amuck (such as the whole random and baseless discussion about how every English phrase is a metaphor (no), and how this is idea is so profound and interconnected with other fundamental truths of the universe (no).
