YC says Markdown has become code in the era of AI workflows

A YC Startup School slide quoted Garry Tan: “Markdown is actually code now.” The surrounding context points to a broader idea that modern teams are using markdown-like artifacts as executable inputs for AI systems.

The slide also mentions building skill files and scheduled jobs, including one finance team example that compiled roughly 100 Excel workbooks into a more automated process.
