The original title is: "The hidden maintenance cost of AI-assisted code: a 6-month retrospective"
Original: 6 Months Later, Nobody Could Read the Code — Including Me
Short summary
A developer shares a cautionary tale of shipping an AI-assisted app with Cursor that became unreadable six months later. A simple feature addition took 9 days instead of 1, with 4 days spent just understanding the existing code. The article details concrete costs — time, money, and lost context — and argues that AI completions optimize for the next line, not for future readability.
- •AI-assisted code shipped fast but became illegible within 6 months
- •Simple feature took 9 days instead of 1 due to lost context and poor code structure
- •Author paid for Cursor twice: once to generate code, once to understand it
Generated with AI, which can make mistakes.
