Chatbots.
- Stateless across sessions — every conversation begins at zero. You re-introduce yourself, re-explain the context, re-set the tone.
- Personality is a system prompt — "act like a therapist" — a costume the next message can take off.
- Drifts with every model release — the answer changes when the underlying model changes.
- No identity to defend — they cannot refuse to break character, cannot hold a stance.
- Useful for one-shot questions — not a colleague. Not a relationship.
