A fleet of agents generates more code in an afternoon than your team used to review in a week. Most of it plausible, some of it confidently wrong, all of it too much to eyeball. The compiler doesn't get tired. Static types check every line the agents wrote before you read one. It's the instinct behind the languages I build on now, Crystal and Rust: pay a little up front, stop paying at 2am. In the agent era that bill just comes due faster.
