A software developer and economist shared reflections on the impact of Large Language Models (LLMs) on programming education and professional competence. While LLMs can collapse the distance between an idea and a functioning system, the author noted a growing risk of building complex software—such as TypeScript/JavaScript systems involving APIs and LLM pipelines—that exceeds the developer's own level of understanding.
Learning Programming in the Age of LLMs: The Risk of Building Systems Beyond One's Understanding
PLUS ULTRA by Amenoyomi
The author highlighted that while AI can resolve immediate errors, it can lead to a gap where the developer no longer fully understands the behavior of the system they have built. This phenomenon raises questions about whether developers are truly gaining competence or merely maintaining the appearance of it.
Regarding learning strategies, the author suggested that LLMs are best used for answering falsifiable questions—tasks with verifiable answers, such as optimizing code syntax—rather than for open-ended inquiries like "what should I learn next?". The author emphasized the importance of understanding the levels of abstraction directly below and above one's current work to maintain effective troubleshooting capabilities.

The gap between the ability to construct a system and the ability to understand it becomes critical during the transition from a prototype to a production product. When AI is used to collapse the distance between an idea and its implementation, a developer may build a complex system—such as those involving APIs, PostgreSQL, and LLM pipelines—that exceeds their own technical level. This gap remains invisible while the system works, but emerges as a significant risk during troubleshooting, where fixing one error may trigger another because the developer does not fully grasp the system's overall behavior.
To mitigate the risk of relying on unverifiable AI outputs, the author suggests limiting LLM queries to falsifiable questions. These are questions that yield answers which can be objectively verified. For instance, asking an AI to make a specific code expression more succinct provides a suggestion that either works or does not work, making it easy to verify. In contrast, open-ended questions such as "what should I learn next?" are avoided because they do not yield a verifiable answer.
Technical autonomy and effective troubleshooting are supported by a strategic approach to abstraction layers. The author's rule of thumb is to understand the level of abstraction directly below and directly above the layer in which one is currently working. This prevents a developer from becoming entirely dependent on the AI for every step of the process and allows them to maintain control over the system's behavior.
While LLMs allow for more directed questioning, the author notes that the fundamental speed of human learning cannot be significantly accelerated. The bottleneck is not the availability of materials or teachers, but the rate at which the human brain can absorb new knowledge. Consequently, achieving true competence still requires the traditional process of trial, error, and systematic study of fundamentals.
