Kind of tangential, but does anyone else worry that systems like these will start to dictate what is "correct" language. Basically pushing narratives subtly through "correcting" totally acceptable speech.
Most people with any writing capability do not use these tools. They are for foreign speakers of English or extremely poorly educated native speakers, they only affect the bottom 50% of written content which is not what affects the development of language.
It's only mentioned in the comment, but the amount of mistakes in tech-related writing, by native English speakers and otherwise, is gargantuan and overwhelming, and I'd wish using something like Grammarly (if safe, open source and so on) was a requirement for putting your writing on the web.
As it is, the quality of writing is so bad, that I (as a foreign speaker) don't improve my English in any way by reading it, and I have to be very careful not to repeat these mistakes in my own writing later.
