Grammarly's expert-review feature can generate feedback through personas associated with recognizable kinds of professional authority, even though the actual experts did not examine the user's work. The product offers the feeling of a panel without the encounter that gives criticism its weight. A writer sees advice framed through a trusted perspective, but the response is a model's prediction of what such a person might say. Expertise becomes a style that software can perform on demand.

Simulated perspectives can still be useful. They may help a writer anticipate objections, test clarity, or escape a stalled draft. The problem begins when a speculative voice is presented with the aura of individual judgment. A real expert brings experience, accountability, disagreement, and the ability to explain why a particular exception matters. A persona supplies recognizable mannerisms without those obligations. As AI products borrow the names and authority of professions, disclosure must describe the relationship plainly. Otherwise, users may confuse access to a fluent approximation with access to the person or practice being approximated. The absent expert is valuable to the system precisely because a reputation can be present while the human labor behind it is not.
