AI Writes the Code, But the Hard Thinking Still Falls on Developers

A developer reflects on how AI-assisted coding tools can rapidly produce functional code, often reducing hours of work to minutes. However, a real-world bug exposed a key limitation: AI handles the expected 'happy path' well but struggles with edge cases that require deliberate product decisions. The author argues that code generated at 85–90% accuracy can be deceptively dangerous, as it looks finished while critical judgment calls remain unresolved. The speed of AI output can also create a false sense of progress, making developers feel behind when they are actually doing the most important work. Ultimately, while AI accelerates the 'how' of coding, the 'why' — understanding intent, context, and consequences — remains a distinctly human responsibility.
