Here is the heart of it, told the way a person might lean across a table and say it after the second glass of wine:
You have never once chosen anything in the pure, free-floating way you thought you did. Every decision that ever felt like yours alone was already being assembled in the dark machinery of your brain, by atoms that once burned inside stars that died before the Earth even cooled. That is not a threat. That is the most liberating thing you will ever learn.
Algorithm follows one continuous thread of cause and effect-from the birth of the universe, through the long death of suns, through the slow assembly of the eye that is reading these words right now, all the way to the next quiet crossroads you will meet. It answers the questions people usually carry to temples and altars, but it answers them with cosmology, evolutionary biology, and the blunt instruments of neuroscience. No hand-waving. No soft consolations. Just the evidence, laid out until it becomes something sturdier than myth.
You will see why the night sky and your own eyes never show you the present-only the past. You will walk the actual evolutionary steps that built vision without any designer at the drafting table. You will understand why knowing that your choices are shaped by forces mostly hidden from you should make you more compassionate, not less accountable. And you will sit with death and love without borrowing a single comfort from religion, and discover that the ordinary objections-meaninglessness, cold materialism, "you can't actually live this way"-crumble when you look at them closely.
