Ah, the documentation dilemma—every engineer’s love-hate relationship! In "The Documentation Delusion: Why Smart Engineers Write Code They Can’t Understand Tomorrow," Terrance Craddock hilariously unpacks the unavoidable truth: even the brightest developers write code today that confuses them tomorrow. The author shares a relatable moment of realizing—after hours of frustration—that the indecipherable mess in front of him was his own creation. He argues that poor documentation is a costly industry-wide problem, with developers wasting 20% of their time deciphering old code. Yet, documentation remains an afterthought, often neglected in the fast-paced world of Agile development. With wit and insight, Craddock suggests that the best way forward isn’t just writing documentation but embedding clarity directly into the code itself.

Key Points:

• "Who wrote this awful code? Oh… it was me." – A humorous and painfully relatable experience of struggling with one’s own undocumented code.
• The Documentation Paradox: Developers avoid writing documentation, only to regret it later when they need to understand past work.
• The Cost of Poor Documentation: Studies suggest developers spend around 20% of their time reverse-engineering undocumented code, equating to lost productivity.
• Agile’s Impact on Documentation: Fast development cycles often deprioritize clear documentation, resulting in long-term technical debt.
• A Better Approach: Instead of relying solely on documentation, engineers should prioritize writing cleaner, more self-explanatory code—names, structure, and comments that clarify intent.
• Best Practices for Documentation: If documentation is necessary, keep it concise, updated, and relevant—think README files, inline comments, and automated tools instead of sprawling, outdated documents.

In short, if you’ve ever found yourself staring at your own code with existential dread, you’re not alone! Want to fix it? Start by writing your future self a clear roadmap—whether in comments, meaningful variable names, or updating key docs. Because if you don’t, tomorrow’s you is in for a long, frustrating day. 🚀
