I wouldn't be able to tell. No load bearing or is not x, it's y.
I actually don't mind if it's good enough, informative and not overly long.
Haven't really read anything super well written (in terms of language and form) lately, other than a really fun hn comment summarizing Trump's War.
But I just haven't read that much lately.
The tell here is the "One ..., then ... <negative>". This is "not X, it's Y" with the clauses reordered.
For some reason the current crop of LLMs are really insistent on generating contrast between two things in every statement.
