THE FILE SYSTEM IS THE NEW DATABASE

Summary from the TLDR Founders newsletter

No database. No API. Just 80+ markdown and YAML files running a full personal operating system for AI agents - and it works better than the fancy alternatives. Agents pull only what they need. A voice encoding system keeps your tone consistent. Memory logs build context over time. The takeaway for anyone building AI-native products is surprisingly simple - your file system might be the best data layer you already have.
