That's very elitist and unfair to people who previously struggled to form their words but now have a better chance at doing so.
The solution to this form of elitism was not to make everyone speak RP, but to encourage non-RP accents, which is more common in the modern BBC.
Your comment seems elitist by encouraging the use of artifice to fit better into an elitist world, rather than breaking down elitism.
For example, you chose to read my response and attack the vocabulary as if that was the point I was trying to make. This is a misunderstanding. I am purposefully reusing the word choice of the comment I'm replying to.
I was trying to very concisely point out that if an LLM is generating your writing it is not your words or your thoughts that you're trying to communicate.
