As AI and agents are adopted to accelerate development, cognitive load and cognitive debt are likely to become bigger threats to developers than technical debt
The term technical debt is often used to refer to the accumulation of design or implementation choices that later make the software harder …

Short musings on “cognitive debt” - I'm seeing this in my own work, where excessive unreviewed AI-generated code leads me to lose a firm mental model of what I've built, which then makes it harder to confidently make future decisions simonwillison.net/2026/Feb/15/ ...

A complication of AI-assisted coding: developers (even if they're being careful, checking everything, etc.) are moving too fast to develop mental maps of their projects and remember their design and architectural choices, making it harder to explain those choices or make changes …

Cognitive Debt. — “Even if AI agents produce code that could be easy to understand, the humans involved may have simply lost the plot and may not understand what the program is supposed to do, how their intentions were implemented, or how to possibly change it.” — margaretsto…

Let that sink in. Even one of the loud and vocal AI proponents such as @simon admits — “I no longer have a firm mental model of what they can do and how they work, which means each additional feature becomes harder to reason about, eventually leading me to lose the ability to …

This whole thing is a good read. I've often referred to “cognitive overhead” when working in engineering organizations pre AI to explain why velocity can grind to a halt, but “cognitive debt” resonates more when it is being deliberately created by AI as opposed to developing ove…
