Written by a professor of cognitive and computational neuroscience, this book is very academic. It goes into the theory of consciousness vs intelligence (spoiler alert, they're not the same). Much detail is given to ideas about how and why we think the way we do. The million dollar question the book aims to answer is what makes us feel we have a unique experience in the world--the sense of "being me" or "being you". Various experiments and tests are cited, as well as new discoveries in the animal world. Near the end of the book, there is even talk of humanoids and just how far machine learning has come in the twenty-first century. I learned a lot from this book and it was not easy to read. I'd much prefer a slimmed-down version more for laymen.
