I don’t really use libraries anymore

AI code generation is fundamentally changing how developers approach dependencies and libraries. Instead of installing packages for common tasks, developers are increasingly using AI to generate custom implementations directly in their codebase. This shift eliminates supply chain risks, reduces dependency bloat, and gives teams full control over their code. Examples include replacing libraries like Tkumi and fast-float with AI-generated alternatives that are simpler to maintain and better integrated. The trend suggests prompts may become the new libraries, with developers sharing prompts instead of packages. This has implications for open source sustainability, as well-documented popular libraries become easier to replace with AI-generated code.
