O'Reilly CPO: When content is free, trust is the product

The executive observed that there is now more technical content than anyone could read in a thousand lifetimes, yet most professionals say they do not know what to trust. AI has deepened that uncertainty.

Historically, editing and verification were the same slow, expensive process. A book could take years to produce and relied on finding authors, vetting them, working with editors, and checking claims with technical reviewers. That labor signaled to readers that claims on the page could be depended on.

With production costs near zero, content is easy to make, but the process behind it is often invisible. The writer quoted Jasmine Sun saying: "Trust is not about information and its quality alone. It's about the messenger. It's about who says it and their track record and what they've told me before."

The CPO argued that expertise is alive and compounds. Content begins to decay as soon as it is published, as frameworks evolve and libraries are deprecated. Keeping expertise alive requires a pipeline of current people and an editorial layer that retires or fixes stale material. O'Reilly works with hundreds of practitioners and treats content in pace layers, from timeless guidance to fast-changing recommendations.

Trust is earned in both directions. Just as PageRank determined importance by links from important pages, reputation is conferred by respected people engaging with and vouching for work. The audience also generates reputation signals, and a publisher amplifies judgments the community is already making.

The article added that AI systems also need trusted engineering knowledge, not just human practitioners.
