Focusing attention can help an animal find food or flee a predator. It also may have led to consciousness. Tracing evolution over millions of years, Michael S. A. Graziano uses examples from the natural world to show how neurons first allowed animals to develop simple forms of attention: taking in messages from the environment, prioritizing them, and responding as necessary.
Then some animals evolved covert attention - a roving mental focus that can take in information apart from where the senses are pointed, like hearing sirens at a distance or recalling a memory.
Graziano proposes that in order to monitor and control this specialized attention, the brain evolved a simplified model of it - a cartoonish self-description depicting an internal essence with a capacity for knowledge and experience. In other words, consciousness.
In this eye-opening work, Graziano accessibly explores how this sense of an inner being led to empathy and formed us into social beings. The theory may point the way to engineers for building consciousness artificially. Graziano discusses what a future with artificial consciousness might be like, including both advantages and risks, and what AI might mean for our evolutionary future.

Disappointing and strangely anachronistic

Almost excellent, and very helpful

For me it lacked a little detail, painting a great picture in broad strokes but not refining the predictions & ramifications of AST, or contrasting it against other theories in a way that helps to differentiate them. But I think for the general public, whose main purpose is something like "understand what consciousness is and how it relates to better-understood systems of information processing", rather than "get testable predictions for designing experiments" or "enumerate detailed subjective ramifications of objective theories of consciousness", the book hits the bullseye.
Thought-provoking survey of consciousness science

Unbelievable scope of work!

(1) that he is merely playing semantic parlor games (ex. 'attention' vs 'awareness');
(2) that there are varying degrees of consciousness (he's pursuing a go, no-go perspective, which is less useful, if not useless);
(3) that he is proposing Perspectives, not hard science, and that the value of perspectives are their useful (if any));
(3) that emotions are used to affect outcomes (usually social), and that they can easily be programmed;
(4) that his grasp of artificial intelligence consciousness is askew, and his potifications on future AI's internal workings are weak.
Interesting was the idea of measuring consciousness.
He has a Philosophy of Death (he does not want to live forever).
He misunderstands mind uploading, in that you will not be uploaded, but only an initial copy of you, which will immediately begin to become different (individualized) with different new experiences.
All in all, he represents Continued Universal Human Cluelessness, and all of the deficiencies associated with it. On that level (philosophical), it was torture for me to listen to. The science was enjoyable.
Clueless on Many Fronts

This book is a swift and Jargon-free journey to the recent advance in neurobiology and especially a computational theory of consciousness. It takes you from the evolution of the conscious brain trough the biological technicality and advantages, the philosophical considerations, and the possible future of conscious machines and mind uploading.
I think that the final chapters on mind uploading and futurism are too speculative. After all, the attention-schema theory of mind does not require a full brain-scan for mind uploading. It is not even clear that you need a neural network for that. Nevertheless, the ideas are mind-blowing and inspiring. A most read to any intellectual.
A conscious spark of joy
