- Separate ML decisioning (who/what to target) from LLM execution (how to write) - most AI SDR stacks conflate these layers leading to poor targeting despite good copy
- Traditional personas are opinion-driven artifacts ('person with coolest turtleneck decides') rather than data-driven buyer profiles - need ML-based preference modeling instead
- Current 'personalization' is just template name-swapping (college, company, recent post) - true relevance requires adapting message structure to audience communication preferences, not just inserting personal details
