💡 The Insight

Modern software stacks are like pyramids - wide at the top, narrow at the base. Hundreds of applications and frameworks depend on just a handful of foundation libraries.

When a foundation project like zlib has a security issue, it affects 15+ billion devices. Yet these critical projects often have just 1-3 maintainers.

"Every project eventually depends on a module maintained by someone in Nebraska who hasn't updated their website since 2003."
