Some people sound like authorities because they are near the work, around the work, or adjacent to the work—not because they are deeply carrying it.

Borrowed authority is one of the most underrated risks in any professional field. It happens when someone becomes persuasive not because they have deeply carried the work, but because they have spent enough time near it to sound fluent around it.

They know the language. They know the trends. They know the talking points. They know how to reference the right issues.

And for many audiences, that is enough. Especially when the audience is looking for confidence more than depth.

But proximity is not mastery. Being adjacent to technical work is not the same thing as doing it at a high level, repeatedly, under pressure, with consequences attached.

That is where the difference shows up. Real expertise is not just knowing what to say. It is knowing what survives scrutiny. What breaks in practice. What matters when the stakes are real. What patterns repeat. What details cannot be skipped.

Borrowed authority can look polished for a long time. The problem is that it often depends on the audience not pushing deeply enough to see where the floor actually is.
