Chapter-by-chapter close reading of David Deutsch's 「The Fabric of Reality」, using Popperian epistemology to take apart AI, morality, and ultimate questions about the universe; hard, falsifiable claims.
27:17The Smarter the AI, the More Moral: Doom Is the Real Relativism
Sam Harris-style doom stories assume intelligence and morality are orthogonal; a genuinely intelligent AI would necessarily understand the value of others, and the notion of a morally frozen superintelligence is just moral relativism.
1:28:35The universe doesn't end in heat death — it gets steered back on course infinitely many times
Tipler's omega point theory was wrecked by his own extravagant religious claims, but Deutsch says there's a valuable core inside: the universe must be continuously piloted to complete infinite computation in finite time.
44:29Knowledge-creators outlive stars, so epistemology is physics
Twist quantum mechanics, computation, evolution and epistemology into one strand, and the conclusion is: as long as humans keep solving problems, the long-term structure of the universe will be determined by knowledge, not gravity.
1:30:56AI Has Not Produced a Single New Theory, So It Is Not an Artificial Person
Deutsch's test: AI only fills in the parts of known theories that nobody has bothered to compute — it is coloring in the existing picture of organic chemistry. To reach the threshold of creating new knowledge, you first need problems — and LLMs have no problems; the problems are the ones we give them.
