Even this comment, while short, is much better! "doesn't have context" is, ironically, kind of context-free. What context did you want? Given what you just said, the answer is apparently "benchmarks." You don't even need to make your comment all that much longer to be much, much better (imho, I'm not dang, I don't own this place, heh)

into something like

Now that I write that out, it's even shorter! But it's way better. You've made a specific criticism of the article, rather than making a very abstract one.

I'd still say that something this short isn't likely to be upvoted, but it isn't likely to be downvoted like you were. Compare your comment to this one: https://news.ycombinator.com/item?id=26446830

While it does start with some "I like Rust," imho that wasn't even necessary. It's also more aggressive than you were, but even got some replies. Even though it contained the same sentiment.
