A Carnegie Mellon study found that AI coding tools produced a three- to five-fold increase in lines of code during the first month, but gains plateaued after two months. Meanwhile, static analysis warnings rose 30% and code complexity increased 41%, indicating persistent technical debt. Sonar highlights that manual code review processes cannot keep pace with AI-generated code volumes, creating bottlenecks and quality concerns when developers rely on the same review methods for exponentially more code.

Key points

  • AI coding tools show initial 3-5x productivity surge followed by plateau
  • Technical debt rises: 30% more warnings, 41% more complexity
  • Manual code review processes become a bottleneck at scale

Summary and key points written by AI from the headline and a short excerpt, so they can be incomplete or wrong. The New Stack did the reporting; read the original for the full story.
