Claude confidently pointed me to a code path in MongoDB's massive infrastructure codebase. I spent an hour investigating it before realizing something was off. The path worked, technically. But there were better approaches - ones the agent had completely missed.
The sixteenth draft of my Chinese dictionary lies abandoned in a folder deep within my repo. Two weeks of work, genuinely good code, completely functional. Pre-AI me would have shipped it just to justify the time spent. Post-AI me deleted it and started building something better. That folder of abandoned ideas tells the real story of how AI changes everything.
