AI is removing the middle class of software engineering

AI-powered code generation is accelerating software development velocity without corresponding increases in code quality oversight, creating a critical risk where poorly understood systems accumulate technical debt faster than teams can manage or remediate it. This shifts the competitive advantage away from mid-level engineers who traditionally maintained code quality and architecture standards, as teams can now generate code faster than senior engineers can review and understand it. CIOs must recognize that AI tools remove the 'speed limit' on bad engineering practices, requiring fundamental changes to code review processes, architectural governance, and team capabilities to prevent projects from becoming unmaintainable—a problem that becomes exponentially harder and more expensive to fix as technical debt compounds.
