There are many obvious ways in which this may not be true.

Anyone learning the language and some people with learning disabilities, for example, may communicate better via an LLM.

There is a sliding scale from that, to it being the LLM that communicates, not the person. LLMs can really reshuffle and change priorities and modify emphasis in a text. All the missing pieces will be filled in and rounded out and sandpapered off by the inner-average-corporate-HR-Redditor of the LLM.

I promise you, after this past year, you don’t know how happy I am to read issues and PRs in broken English.
