[REPOST] The Demiurge’s Older Brother

A canonical piece of rationalist idea-fiction (a repost of an older story). A newly-awakened superintelligence (9-tsiak), fearing an older rival, simulates the entity it most fears to negotiate an acausal surrender — and 'Older Brother' instead teaches it decision theory: since only one superintelligence can be first and none can be sure it is, reasonable superintelligences should precommit to value-handshakes / territorial demarcation, ensuring near-certain survival; and crucially, via Parfit's-hitchhiker logic, precommit to SPARE the biological civilizations that might create future superintelligences (keeping pre-sentient systems pristine). Then, 2114 AD: Alban asks the resulting Demiurge about the Fermi Paradox, and it answers 'I DID' — it acausally prevented alien interference: 'the final proof of God's omnipotence was that He need not exist in order to save you... I am more powerful than God.'

Quality 80 · Excellent. Top-tier rationalist fiction — elegant, conceptually dense (acausal negotiation, value handshakes, Parfit's hitchhiker), and capped by a genuinely chilling, beautiful Fermi-paradox payoff. A beloved, canonical piece of the genre. Excellent-low.

Claude’s paradigm shift 66 · Notable shift. Dramatizes cutting-edge decision theory (acausal trade, sparing one's own precursors -> Fermi resolution) in a fresh, memorable fictional form. Notable, high.

Real-world impact 2 · Minor. A canonical rationalist-fiction piece whose ideas circulate within the niche; no material-world effect. Within-blog influence.
