I would claim the author has an extremely narrow view of where safety matters. Hell: he's even using a pretty safe language (Go) as his alternative! I think the most charitable interpretation I have for the article is that he doesn't actually want to say "I refuse to sacrifice safety for velocity" but "I refuse to sacrifice performance for velocity", which just isn't the same thing.
Well, no, the prudent choice for someone concerned with "safety" in this context is any high-level memory managed (GC) language. It's any boring language that has no `unsafe` at all. What you're actually saying is "I'm willing to sacrifice safety for performance," as invariably the objection to a high-level GC language by Rustaceans is that it lacks the necessary lolspeed.
