Vibe Coding Is Making Us Faster — And Dumber At The Same Time

A 16-year-old’s honest confession about shipping code he didn’t understand. I built 200+ files last month. I used Cursor. I used Claude. I used every AI tool I could find. The code worked. Features shipped. Everything looked great. Then someone asked me to explain how my authentication middleware worked. I couldn’t. Not because I forgot. But because I genuinely never knew. I had accepted the AI’s output, seen it work, and moved on. Repeat 200 times. That moment was uncomfortable in a way I hadn’t expected.
