The Vicious Cycle of Technical Debt Triggered by AI Code Generation

The rapid advancement of AI models in code generation is creating significant structural distortions within the software development industry. An essay titled “We’re Going to Make Out Like Bandits,” published on rocketpoweredjetpants.com via Lobsters, sharply critiques this ongoing vicious cycle. The author estimates that this process, which is expected to take about five years in total, is already 1.5 to 2 years underway.

The Disappearance of Junior Developers

The point at which AI models reached a “sufficient” level in coding has marked the beginning of a troubling trend: companies are now treating junior developers as a cost-cutting target. The rationale is that the same budget can purchase a large number of tokens to generate significantly more output. This shift is already evident in the job market, where a decline in junior positions is being observed.

While this move may lead to short-term productivity gains, it severs the talent pipeline in the long term. If junior developers are deprived of opportunities to gain experience and advance to senior roles, the industry will face a shortage of skilled developers capable of making high-level decisions in the coming years.

Codebase Bloat and Duplication

Large Language Models (LLMs) excel at generating new code. By leveraging the vast patterns included in their training data, they can effortlessly produce auxiliary functions and methods sourced from third-party libraries. As a result, repository sizes are ballooning rapidly.

However, AI lacks the inclination to autonomously organize code, eliminate duplication, or improve maintainability. While the context window of these models continues to expand, it is still insufficient to encompass entire modern large-scale repositories, leading to frequent inconsistencies with existing code. Most AI-generated code tends to be additive in nature, often resulting in redundancy.

Surpassing the Complexity Threshold

Machines are inherently more tolerant of complexity than humans. Consequently, development organizations have become increasingly willing to accept levels of technical debt that would previously have been deemed unacceptable. While AI is adept at reading code and tracking control flows, this capability often serves to obscure complexity rather than resolve it.

Brian Kernighan’s famous quote—“Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it”—is particularly relevant to complex AI-generated code. At some point, the accumulation of technical debt and complexity may exceed even the AI’s ability to manage it, and instances of codebases that have surpassed human comprehension are already becoming evident.

A Whack-a-Mole Game of Bugs

AI-generated code generally has a higher defect rate compared to human-written code. Even if the defect rate were to fall below that of human developers, the sheer volume of generated code means the absolute number of bugs will still increase. Since much of this code is not properly refactored, fixes in one area often fail to propagate, turning bug fixing into a never-ending whack-a-mole game.

Senior Developer Burnout and Talent Shortage

Only experienced senior developers have the expertise to organize bloated, unstructured codebases and address the mountain of duplication and bugs. However, they are increasingly facing severe burnout—reported to have spiked by 22%, according to the article—due to the burden of managing the excessive complexity created by AI. Many are leaving the industry as a result.

With junior hiring halted, there is no pipeline to develop new senior developers to replace those departing, exacerbating the talent shortage.

Editorial Opinion

Short-Term Impact The decline in junior hiring and the degradation of codebases currently being observed are likely to accelerate further over the next 3 to 6 months. As AI models improve, companies are expected to prioritize short-term productivity gains, further reducing investments in human talent. However, there are already signs that the accumulation of technical debt could manifest as significant project delays and quality issues. The critical question is when this balance will tip.

Long-Term Perspective Over the next 1 to 3 years, the shortage of senior developers is expected to become more acute, making it increasingly difficult to maintain large codebases. If the industry runs out of professionals capable of evaluating and improving AI-generated code, the overall reliability of software systems could be at risk. The industry will need to redefine not only “how to write code” but also “how to read and discard code” on a broader scale.

Questions from the Editorial Team In a development process that relies on AI-generated code, how should new metrics and practices for managing technical debt be designed? Additionally, instead of eliminating junior developers, how can they be nurtured using AI to develop their skills?
