I think the derailment of this thread into "is Rust's memory safety good or not" is unfortunate and tedious (this debate must have happened
hundreds of times by now on this site alone), but I also think it's unfair to lay the blame on Steve for this. Steve left a thoroughly glowing comment praising Zig's work on compiler performance, and comparing to his perspective on the early days of Rust. He mentioned in passing that he's not a Zig user due to preferring to work in memory-safe languages, which was polite, brief, clearly his personal position, and in my opinion an acceptable way to disclose his relationship with Zig without derailing the thread to be about memory safety.
This comment spawned two subthreads. One of them was focused on the differences between Rust and Zig's compilation model, which is directly relevant to the article and illuminating regarding the engineering tradeoffs.
In the other subthread, pron posted paragraphs and paragraphs arguing about what memory safety really means and whether or not Steve is right to have his opinion that Rust is "safe". This tangent had essentially nothing to do with the content of Steve's comment; it (and not Steve's initial comment) was the point where the thread was derailed from the topic of Zig's incremental compilation model. Steve responded politely in this thread to comments and questions directed at him, but did not fan the flames or take the thread further into off-topicness. If the moderators collapsed pron's comment or detached it and pinned it to the bottom of the page, this comment thread would be much better and much more respectful to the Zig project.
I think the RESF trope is just about dead now; it's given way to the Rust Detractor Strike Force showing up to turn unrelated threads into tangential arguments about why Rust is bad.
