Why did I create this video?
The AI coding community is obsessed with chasing the latest tools, but as a senior engineer, I know this approach is backwards. Here I demonstrate with a real bug-fixing scenario why mastering ONE tool deeply is far more valuable than constantly switching between Claude Code, Codex, and whatever launches next week. This is the reality check the hype-driven AI coding space desperately needs - these tools break, and when they do, your actual programming skills are what save you.
