LLMs are living off the moral and intellectual capital of a pre-AI world, just like Nietzsche said secular liberals live off Christianity. What happens when the inheritance runs out? Using LLMs well — knowing when to trust them, how to interrogate their outputs, what questions are worth asking — depends on capacities that are pre-LLM in origin: critical judgment, domain expertise, philosophical seriousness, taste. People who use LLMs well right now tend to be people formed by traditions of deep reading, argument, and intellectual discipline that were not themselves produced by or optimized for interaction with language models. The tool works for them because they bring something the tool cannot supply. Nietzsche thought secular liberals were coasting on the fumes of a Christian metaphysics they'd officially abandoned. The shadow of God lingering on the cave wall. The question is whether LLM-native thinking is the same kind of afterglow.
