AI coding agents generate more code, but not more software

Anyone who has even tangentially associated with computer programming knows that modern AI coding assistants and agents can be incredibly efficient at generating huge amounts of functional code . But coders making use of those tools also know better than to trust the accuracy of that code , meaning substantial effort needs to be spent reviewing any AI-generated output. A recent study of actual coding practices across hundreds of firms finds that human code review forms a significant "bottleneck"
