"The Sampler Is Not the Sampled": A Debate on Whether AI Personas Really Exist
gerardsans · x · 2026-10-22
Gerard Sans weighs in on a debate about LLM persona ontology with the framing "the sampler is not the sampled."
- Text sampling has no mechanism for becoming a character like Harry Potter — it only generates text that sounds like that character
- The sampler does exist as a computer program running a transformer in memory, but it has no personality of its own
- He adds that "you" as a character in a conversation is merely inferred by the AI and doesn't exist outside it, unless the same training data and priors are reproduced
- The opposing view treats AI personas like fictional characters: they exist in text form as long as they remain recognizable and can appear in new novels
