Kyle Kingsbury warns of eroding trust in software and documentation in the age of LLMs

Kyle Kingsbury, author of the Jepsen testing tool, warns that LLMs are eroding trust in software, documentation, and the organizations that create them, because traditional quality signals can now easily be faked.

Kyle Kingsbury, author of the Jepsen testing tool used to verify the correctness of distributed systems, has warned that the spread of LLMs is eroding trust in software, its documentation, and the organizations that create it. According to him, engineers may start approaching new software projects with distrust, because signals that previously served as a mark of a system's maturity and quality can now more easily be faked. Kingsbury poses the question of what project maintainers can do in the age of LLMs to ensure the correctness of software and the accuracy of documentation, and how to subsequently demonstrate that quality to users.

The quote comes from a text titled "Jepsen results for ParticleDB 1.1.4" and was published on the Simon Willison blog under the topics ai, generative-ai, llms, and ai-misuse. The available excerpt is short and contains only a general warning without a concrete solution or further technical details about the database test in question for ParticleDB. See the source article for details.

What changed

Why it matters

If previous markers of software quality (documentation, test descriptions, changelogs) can easily be imitated using LLMs, both users and companies lose a reliable basis for deciding whom to trust. This increases the pressure to rely on one's own testing and independent verification, rather than on a project's external presentation.

Two audiences, two different impacts

What this means

01

For individuals

Developers and software users should approach documentation and descriptions of new projects with increased caution, because LLMs make it easy to produce text that looks trustworthy without corresponding to the actual quality or testing of the code.

What to do When evaluating a new software project or library, verify quality through your own testing or an independent source, not just based on documentation or marketing claims.

02

For a business

Companies that adopt open-source components or documentation from vendors should expect that traditional signals of a project's maturity and quality (documentation, test descriptions, changelogs) can now easily be generated using an LLM, and are therefore not automatically proof of actual quality or security.

Risks and compliance
What to decide Consider strengthening internal verification of the quality and security of third-party software and documentation (code review, tests, audits) instead of relying on external trust signals.
