The Problem With AI-Generated Code: Maintenance Debt in the Fast Lane

The Cost of Comprehension

Writing code was never the bottleneck in software engineering. Reading, understanding, and maintaining code has always consumed 90% of a developer's time.

With AI coding assistants, the velocity of code creation has increased by an order of magnitude. But human reading comprehension speed remains unchanged at approximately 200–250 words per minute.

"When generating code costs zero effort, the cost of understanding and defending that code approaches infinity."

The 'Looks Correct' Trap

The most dangerous code is not code that breaks immediately with a syntax error. The most dangerous code is code that looks plausible, compiles without warnings, passes happy-path tests, but fails subtly on edge conditions because the author never formed an internal mental model of its execution path.

Writing as a Filter

This technical journal exists precisely to fight that degradation. When you force yourself to write about how a system works—explaining the architecture, documenting the trade-offs, and admitting what failed—you are forced to understand it.

We do not write because we know everything; we write to find out what we don't know.
