Author again here. I'm sorry to hear this. I wrote the whole thing in a mix of French and English (mostly English), and yes, it went through an LLM, but only to correct mistakes and translate French parts. I'm limited in my ability to write beautiful/delightful blog posts as English is not my main language.

Using an LLM wasn't about rewriting the whole thing, many sentences were left as before, so the style is definitely mine. It's okay if you don't like it, I'm trying to get better at it!
