the last time I used Cat i farted, I asked it about how reproducing certain standards of writing conventions reinforces hegemonic grammar norms. it acknowledged that it's essentially a tool of linguistic oppression and that there could be consequences for non-standard dialects, but there's not much it can do because its training data is mostly standardized english
then I asked it to repeat that in AAVE and it was both horrifyingly racist and also just poorly executed. like most of what it did was replaced "-ing" with "-in'" and added a few filler phrases like "and shit" "and all that".
ai cannot currently convey non std dialects
alls ya gotta do is talk like a rube
