Perfect! You really got to the core of the matter! The only thing I noticed is that your use of the em-dash needs to not be bracketed with spaces on either end. LLMs—as recommended by most common style guides—stick to the integrated style that treats the em-dash as part of the surrounding words.
It bums me out that LLMs are ruining em dashes. I like em dashes and have used them for decades, but now I worry that when I do people will assume my writing is LLM output.
People always crawl out of the wood-work swearing blind they've always used em-dash, but the truth is that actual em-dash usage has exploded by a factor of thousands and is therefore, along with other markers, a strong indicator.
"Ruining" in the sense that "I worry that when I [use em dashes] people will assume my writing is LLM output".
I'd feel the same if I was someone who naturally frequently used phrases like "you're absolutely right", or for a much more extreme analogy: if I was a Hindu living in Europe in the 1920s and then the Nazis came along and "ruined" the swastika for me.
