Context Portability — “Memory Is the Moat” (Nate’s Newsletter)

Summary

Nate frames accumulated AI interaction history as “professional capital” that users don’t own. Six months of daily use produces qualitatively different output — “40% right” to “80% right.” Four loss points: tool switching, company mandates, job changes, platform terms. Proposes “Bring Your Own Context” (BYOC) — portable AI memory bundles transferable between Claude, ChatGPT, and other systems.

Core claim: Memory has become the moat, not model capability. Switching costs are real, growing, and unmeasured.

Implications

Inverts the vendor vertical advantage. The more surfaces you use (Claude Design + Claude Code + Claude for Word), the deeper your context lock-in. BYOC is the architectural counter-proposal: decouple context from vendor. This is the structural tension that will define the next competitive phase.

Connects directly to GitHub Copilot opt-out deadline (April 24) — platforms capturing the interaction data that constitutes this “capital.”
