The 30-second cache rule

Cross-AI portability is the structural moat OpenAI and Anthropic can't build for themselves. The user's context, exported as a public URL, becomes infrastructure that survives any single vendor's pivot. That's why the right primitive isn't an API key — it's a permalink.

The hardest part of a 1-person startup isn't the work — it's the lack of a forcing function. Without a meeting on Tuesday, nothing has to ship on Monday. The schedule has to come from somewhere, and "because I said so" isn't enough.

Markdown won because it was always good enough. Not the best at any one thing — never the fastest editor, never the prettiest output, never the most semantically rich. But always close enough that the switching cost killed every alternative.

The thesis here^[1] is that delivery model matters more than retrieval quality.
