I think you are right, but it also makes sense. Human communication is inherently inefficient.
Points of view, miscommunication, interpretation... It's the obvious point to automate.
Not defending it, just my thoughts
I have a couple of colleagues that run all communication through an LLM. It really helps their writing, but it does nothing to help their understanding.
It also makes me hate communicating with them because they'll (somewhat obviously) prompt the LLM to make the conclusion they want. For example, "respond to this jira with why this isn't an issue"
