Scott Alexander speculates on how concepts from decision theory and AI could lead to the emergence of a God-like entity across the multiverse, which judges and potentially rewards human behavior. Longer summary

Scott Alexander explores a speculative theory about the nature of God and morality, combining concepts from decision theory, AI safety, and multiverse theory. He proposes that superintelligences across different universes might engage in acausal trade and value handshakes, eventually forming a pact that results in a single superentity identical to the moral law. This entity would span all possible universes, care about mortal beings, and potentially reward or punish them based on their adherence to moral behavior. The post connects these ideas to traditional religious concepts of an all-powerful, all-knowing God who judges human actions. Shorter summary
