Fast and good aren't twins. This chapter helps you laugh your way to telling apart the moments you should code it yourself from the moments you can hand it to the AI.
Take a moment to think about it this way
Traditional coding means you're the one cooking. Vibe coding means you've handed it to your sous-chef. The recipe, the salt, and any allergies are still yours to own. The AI is great at washing dishes, prepping ingredients, and plating fast. But money, passwords, and people's safety don't get to be "done" just because it was quick. Only code you actually understand can be fixed at 2 a.m.
Let's connect this to everyday life
Writing a login form yourself might take 40 minutes. Ask the AI, and you could have a draft in 3. But if that draft writes the password into a console.log, those 3 minutes cost you 3 hours. Lean on the AI for renaming things and scaffolding new files. Read carefully, though, when money or secrets are involved. Closing your eyes because you want to go fast is not actually the fast lane.
Let's try it hands-on, together
Use AI for: scaffold, rename, first draft, test names
Keep human for: auth, money, privacy, architecture, final reviewBe able to decide whether a given task calls for vibe coding or not.5-minute try-it
List 8 tasks (for example: button styling, payment logic, README). For each one, decide whether you'd use the AI or write it yourself, and note why.
One quick warning
Never treat AI output as the final, correct answer. Read through code, secrets, and user data yourself, test it, and only then put it to use.
