Carson Gross argues Markdown files are becoming software's true source code

In an essay, Montana State University professor and consultant Carson Gross describes a shift he has observed in client organizations adopting agentic coding: Markdown documents are increasingly the source of truth for systems, with LLM-generated code treated as a derived, low-level artifact. He cites Hartley Brody's earlier essay 'Markdown is the new source code' to support the observation, and argues that Markdown specs should be checked into /src alongside the code and tests they generate, rather than living only in transient prompt sessions.
