• Coding models are worst at exactly the thing an AI research explosion would need: code that has never been written before. AKAndrej Karpathy17 Oct 2025
• AI models are not yet capable of producing great code DHDavid Heinemeier Hansson16 Dec 2024
• The code today’s models and agents write is very hard to follow: you get better performance without knowing why, and no way to fix it when it breaks. ESElizabeth Stone19 Jul 2026
• The prediction that 90% of code will be AI-written by the end of 2025 deserves skepticism, though manual programming may yet become a horse: ridden for love, not transport. DHDavid Heinemeier Hansson12 Jul 2025
• Whether agent-written code needs to be good depends entirely on how long it will live: a throwaway single-page tool can be spaghetti, anything maintained cannot. SWSimon Willison19 Mar 2026
