The author comes from a completely different culture than most of HN users. English doesn't seem to be their first language. It can be hard to formulate your thoughts without sounding weird to native speakers, I know that feeling perfectly well.
But maybe AI is better than I think.
I'm Dyslexic and have had to cope with people criticising my writing, judging my ability based on simple mistakes, it hurts and I'm sorry you have had that today.
I haven't had the chance to fully read it yet, but I'm going to later as it's super interesting to me.
