Introduction

What is technological debt and how does AI amplify it?

Traditional technological debt versus its new, generative form

Traditionally, technological debt arose from time pressure, budget constraints, a lack of appropriate skills in the team, or simply conscious project compromises ("we'll do it properly later"). It was a largely manual and controlled process, though often insufficiently documented. The introduction of artificial intelligence-based tools, such as coding assistants, fundamentally changes this dynamic.

The generative form of technological debt is much more insidious. AI can produce thousands of lines of code in minutes—a volume that would take a programmer days or weeks to create manually. This scale means that even a small percentage of low-quality, suboptimal, or error-containing code accumulates at an alarming rate. The problem is that AI-generated code often "works," passes basic tests, and looks correct at first glance. The true costs only become apparent in the maintenance, scaling, or integration phase with other systems.

Main sources of AI-generated technological debt

To effectively manage this risk, one must understand how AI generates technological debt. The main causes can be classified into several areas:

1. Lack of full business and architectural context: AI models, despite their impressive capabilities, do not have a deep understanding of your business specifics, the long-term product vision, or the existing system architecture. The code they generate may be functional in isolation but may not fit into the broader strategy, leading to inconsistencies and future integration problems.


2. Generation of suboptimal code: AI often takes the "easy way out," proposing solutions that are most common in its training data but not necessarily the most efficient or scalable for a specific use case. This can result in performance issues, excessive resource consumption, and the need for costly refactoring in the future.


3. Replication of bad patterns (Code Smells): AI models learn from vast repositories of publicly available code, which is not always a model of quality. As a result, tools like ChatGPT in programming can unknowingly replicate and perpetuate bad practices, outdated libraries, or insecure language constructs, poisoning an organization's codebase.


4. "Hallucinations" and non-existent code: It sometimes happens that AI generates references to non-existent functions, libraries, or APIs. A less experienced programmer, trusting the tool, might waste hours debugging a problem that stems from a faulty automated suggestion. This is a straight path to frustration and accumulating more layers of debt in an attempt to "fix" a non-existent problem.


5. Dependence on the black box: When a programmer accepts a piece of code without fully understanding how it works, they create a "black box" within the system. In the future, when this code requires modification or repair, the lack of knowledge about its internal logic will significantly prolong and complicate the process, generating high "interest" costs on the incurred debt.

Risks associated with using AI in software development

Hidden errors and security vulnerabilities in AI code

One of the most serious threats is the introduction of subtle security vulnerabilities into the code. AI models, trained on diverse and not always secure data, can generate code susceptible to attacks like SQL Injection, Cross-Site Scripting (XSS), or other common threat vectors. The problem is that these vulnerabilities are often not obvious. The code may be syntactically correct and functionally sound, yet contain improperly validated input data or use outdated, vulnerable cryptographic libraries. The speed at which AI generates code can cause the number of potential attack vectors in an application to grow at a rate that traditional code review processes cannot handle. This creates a false sense of security, while in reality, the attack surface of the company's systems is systematically expanding.

The "black box" problem and lack of code understanding

As mentioned earlier, the tendency to accept AI-generated code without a thorough understanding of its operation is a straight path to disaster. This phenomenon, known as the "black box problem," has far-reaching consequences.

Firstly, it makes debugging difficult. When an error appears in the system, and its source lies in a complex piece of code that no one on the team fully understands, the time needed for diagnosis and repair increases exponentially. Secondly, it stifles competency development. Junior programmers, instead of learning to solve problems and understand the fundamental principles of software engineering, can fall into the trap of mindlessly copying and pasting AI suggestions. In the long term, this leads to an erosion of technical knowledge within the team and a dependency on external tools, which is a strategic risk for any technology organization.

Maintenance and refactoring costs of AI-generated code

The initial time savings achieved through AI in programming can be more than offset by subsequent maintenance costs. Code that is suboptimal, poorly organized, or tightly coupled is much more expensive to modify and extend. Each new feature requires more implementation time because developers must first "break through" the layers of accumulated debt.

Refactoring, the process of improving the internal structure of code without changing its external behavior, becomes inevitable. However, refactoring AI-generated code on a large scale is a huge undertaking, requiring the involvement of top engineers and halting work on new features. From a CTO's perspective, this means allocating significant budgets and resources not to innovation, but to "cleaning up" after the tools that were supposed to accelerate innovation. An effective code audit and early problem detection thus become not a luxury, but an absolute economic necessity.

The role of the programmer in the age of artificial intelligence: From creator to supervisor

Will Claude Code and ChatGPT replace programmers? An analysis of the facts

The question "Will Claude Code replace programmers?" is one of the most frequently asked in the industry. The answer, at least for the foreseeable future, is no. These tools are incredibly powerful assistants, but they lack key attributes that define the value of a good software engineer:

• Understanding of business context: AI does not understand the company's strategic goals, the end customer's needs, or market nuances. It is the programmer who must translate these requirements into concrete technical solutions.


• Architectural thinking: Designing scalable, secure, and maintainable systems requires vision and the ability to anticipate future needs. AI operates at the micro-level (code snippets), while a human is essential at the macro-level (system architecture).


• Critical thinking and problem-solving: AI can generate solutions to common problems, but for complex, non-trivial challenges, human creativity, the ability to abstract, and experience are irreplaceable.


• Accountability: Ultimately, it is a human, not an algorithm, who is responsible for the software's operation, its security, and its quality.

New key competencies: Prompt engineering and critical code assessment

This role transformation requires the development of new skill sets. As a CTO, it is crucial to identify and promote these competencies within your teams to fully leverage the potential of AI while minimizing risks.

1. Prompt Engineering: This is the art and science of creating precise, contextual queries (prompts) for AI models to achieve the desired result. A good prompt engineer knows how to "talk" to the AI so that the generated code is as close to expectations as possible—secure, efficient, and compliant with the company's standards. This is a skill that directly translates into quality and reduces subsequent rework.


2. Critical code assessment: The programmer of the future must, above all, be an excellent code reviewer. Instead of blindly accepting AI suggestions, they must be able to quickly evaluate them for correctness, performance, security, and readability. This requires deep fundamental knowledge and experience. The ability to quickly spot subtle errors and potential technological debt in AI-generated code is becoming one of the most important competencies.


3. Systemic and architectural knowledge: In a world where writing individual functions is automated, the ability to see the system as a whole becomes even more important. Programmers must become mini-architects, understanding how individual components interact, what their dependencies are, and how changes in one place will affect the rest of the application.

Code audit as the key to quality management in the age of AI

Specifics of auditing AI-generated code

An audit of AI-generated code differs from a standard review. It requires auditors (programmers) to change their perspective and focus on the specific threats posed by generative tools.

The key areas that require special attention are:

• Verification of logic and intent: The auditor must ask not only "Does this code work?" but more importantly, "Does this code do exactly what it's supposed to do, and nothing more?". It must be verified that the logic implemented by the AI is fully consistent with business requirements and does not introduce undesirable side effects.


• Searching for "hallucinations": All references to external libraries, APIs, and functions must be scrupulously checked to ensure they are not the result of an AI model's "hallucination."


• Security assessment: Every piece of code, especially that which handles input data or performs cryptographic operations, must undergo a rigorous analysis for known vulnerabilities. It should be assumed that the AI may have unknowingly implemented an insecure pattern.


• Performance and resource consumption analysis: AI-generated code can be inefficient. The audit should include an assessment of algorithmic complexity and the potential impact on system performance, especially in critical execution paths.


• Compliance with standards and architecture: The auditor must act as a guardian of architectural consistency, verifying that the new code complies with the organization's adopted design patterns, naming conventions, and overall application structure.

Tools and processes supporting an effective audit

An effective audit in the age of AI relies on the synergy between people and technology. Implementing the right tools and formalizing processes is essential for scaling quality control.

1. Automated static analysis tools (SAST): These tools scan source code for known error patterns, security vulnerabilities, and code smells. In the context of AI, the configuration of these tools should be extended with rules specific to problems frequently occurring in generated code (e.g., lack of validation, use of deprecated functions).


2. Rigorous Code Review (peer review): No tool can replace the critical eye of another experienced engineer. A mandatory peer review process should be introduced for every piece of code created with significant AI assistance. This process should be formalized, with clear acceptance criteria.


3. "Pull Request" culture with clear guidelines: Working based on Pull (or Merge) Requests, where every change must be approved by at least one other team member, becomes an absolute foundation. The description of such a request should clearly indicate which parts of the code were generated or assisted by AI, allowing reviewers to be particularly vigilant.

Building a culture of quality and responsibility in the team

Ultimately, the most effective tool in the fight against technological debt is a strong organizational culture. As an IT leader, you have a key influence in shaping it. An environment should be promoted where quality is the shared responsibility of the entire team, not just the task of dedicated testers. Programmers must feel that they are rewarded not only for the speed of delivering features but, above all, for creating robust, secure, and maintainable code. This means promoting open discussion about technological debt, allocating time for refactoring, and treating code audit not as a cumbersome bureaucracy, but as an integral part of professional engineering craftsmanship.
