Most Wikipedia work is taking paywalled academic content and summarizing it in an encyclopedic format.

For programming, agentic AI can find most of what it needs because everything is open access on Arxiv, blogs, or in the codebase itself. That's why it can "magical oracle" answer questions that were limited to good prompting.

For most other professional topics, citations are locked behind paywalls. Wikipedia editors get free access to academic libraries, but the readers don't. That's why consumer tools suck.

When the big AI companies integrate with proprietary databases in fields like history or social sciences is the time when Wikipedia dies for answering questions.
