A Thousand Brains by Jeff Hawkins

4.0

Rating: 8/10
Duration: 7 days
Topics: Neuroscience, Neocortex, Learning, Intelligence


The book is split into three parts:
Part 1, explores the human brain as we know it + introduces Hawkin's theory of intelligence
Part 2 explores the relationship between Hawkin's theory and AI and how it'll impact our future
And part 3 explores Hawkin's theory and its relationships with human intelligence

I don't have a background in neuroscience but I enjoy reading and learning about the subject, so I was excited to read A Thousand Brains. Despite my limited knowledge of the subject, Hawkin does an incredible job at simplifying complex concepts, making the book an appropriate read for anyone.

The book itself is very niche. Hawkins discusses neuroscience as a whole but his theory specifically focuses on the neocortex, the most outer layer of the brain (also referred to as the new brain)
Using research and logical deduction, Hawkins proposes a new theory about the neocortex and intelligence, called the Thousand Brains Theory of Intelligence.

Although Hawkin's theory itself is simple, there are many components that are needed to help readers fully understand his theory (for the sake of this post, I won't explain them but I will at a future date).
Similar to a puzzle, Hawkins does a great job of putting the pieces of his theory together, building on both old and new research to help draw his hypothesis.

Hawkin is an incredible writer and a brilliant mind and for the most part, I enjoyed reading his book. Part 1 was the most interesting to me, but parts 2 &3, which focus on the relationship between his new theory and AI & human intelligence, put me in a slump.

Overall a great book worth studying, especially if you're interested in learning about the neocortex. If you enjoy reading books that are more scientific in nature, then I'd highly recommend reading this book.

Fun fact: this book was one of Bill Gates's favorite books of 2021!
