Why people love it

  • Intelligence without consciousness explored · 8

    something about the way it described agency without consciousness was both creepy and extremely memorable

    Apr 2026 · comment

    the aliens being intelligent without being conscious was fascinating and gave me a different perspective

    Oct 2026 · comment

    The book makes pains to draw a line between consciousness (or meta consciousness) and intelligence.

  • Thought-provoking take on first contact · 4

    still one of my all time favorite sci fi books. A fantastic exploration of intelligence, conscioussness and first contact.

    Oct 2026 · comment

    easily the most thought provoking take on consciousness and first contact i have encountered in years

    May 2026 · comment

    Blindsight dismantles a lot of noble myths about what it means to be human and human exceptionalism.

    something about the way it described agency without consciousness was both creepy and extremely memorable

    Apr 2026 · comment

    gave me the same feeling of "this is incredibly alien and I have no idea what will happen next"

    Mar 2026 · comment

    It has the creepy, psychological bent of Annihilation combined with the hard science elements

  • Dense with ideas, rewarding read · 5

    Managing to combine a dozen ideas from previous works into a coherent whole is far from uncreative.

    Oct 2026 · comment

    this is a new idea dense book to say the least - if you love worldbuilding, please pick it up

    Oct 2026 · comment

    thought it was a decent attempt along with many other ideas in the book, very enjoyable to me

What people warn about

  • Hard to follow, dense writing · 4

    The writing definitely felt try-hard, especially at the start where the first few chapters seem really obscure by design.

    Oct 2026 · comment

    I found the writing really hard to follow. And it was really difficult to visualise any scene due to how complicated it all was.

    Oct 2026 · comment

    it's a dense, perhaps 'dry' read for some - but very rewarding nonetheless IMO

    Feb 2026 · comment
  • Space vampires feel distracting · 4

    The book would have been better if the author had left out this vampire nonesense. All in all, it was a bit of a drag to read.

    Oct 2026 · comment

    a scifi book about posthuman vampires that has been deliberately engineered to make a philosophical point

    May 2026 · comment

    The problem for a lot of readers is it's distracting while not adding anything substantial.

    Oct 2026 · comment
  • Weak, aimless plot · 4

    wrapped in a mediocre action movie plot that becomes nonsensical by the end

    Apr 2026 · comment

    It's just a collection of "isn't that cool" pop-sci phenomena randomly dropped into an Aliens (1986) space horror plot.

    Oct 2026 · comment

    boring, marginally pretentious book. Tries to bring up some interesting ideas, but loses the plot along the way

    Oct 2026 · comment
  • Overstated argument against consciousness · 3

    I really think it oversold the case against consciousness and for belligerent intelligent life.

    Jun 2026 · comment

    Second, the book rests on the assumption that consciousness is cheap enough that its metabolic costs are irrelevant.

    Oct 2026 · comment

    the conclusion, that non-consciousness is somehow "Better™," falls absolutely flat for me
