Introduced in early Linux as a way to expose internal kernel data, /proc turned introspection into a superpower. Need to see CPU info? Memory usage? Active processes? It’s all just files. Unlike traditional tools that queried the system with custom code, /proc let you cat your way into real-time diagnostics. It's a filesystem, but it doesn't store data—it tells the story of your system in live detail. Even now, it's essential for system monitoring and scripting.
