inertia. Observers are waiting for a killer app to sway the masses. Obviously memory safety isn't a killer feature in many eyes, because they trust their abilities, would have to go all out using the unsafe environment or they don't see the benefit of one less class of bugs over other concerns. If they did any of that, they would at least be using e.g. java already - on another note I'm only waiting for rustc's first security relevant bugs to be reported, that are supposedly impossible.

I heard the name was a play on words on a one-of-error concerning Trust.
