comprehension debt

background

the (known) origins of the term "comprehension debt"

Jeremy Twei coined the perfect term for this: comprehension debt. It’s certainly tempting to just move on when the LLM one-shotted something that seems to work. This is the insidious part. The agent doesn’t get tired. It will sprint through implementation after implementation with unwavering confidence. The code looks plausible. The tests pass (or seem to). You’re under pressure to ship. You move on.

symptoms

  • volume & verbosity inflation; PRs grow in size, making diffs harder to review & reason about.

Expertise and interviews

In 2001 Paul Graham, founder of Startup Incubator Y Combinator wrote a blog post about LISP called 'Beating the averages'. I don't want to talk about LISP, or startups, not today anyway.
