To be very frank, nothing in the blog post is ground-breaking or interesting enough to be on HN. The only thing it has is its (probably knowingly) controversial title, and as such, I have no problem directing technical and nit-picking ire at it.
For starters, I'm talking about @Ferret7446's post, so I don't know why you are talking for them.
Still, if the lack of something of note was the main issue, just say that. Nitpicks like these are only informative to people who doesn't know how computers work. They can serve as fun tongue-in-cheeks, but that was seemingly not the intention here.
As it stands, in my eyes, this just a small fun project. How is the title even controversial? Because it has "Rust?"
