I mean, there's a safety aspect, as there's definitely been issues in codecs and what not before.
Not particularly sure I trust that to a single young reddit poster tho. This mostly seems like a hobby project that got away from the dev via memes.
Don't forget copious amounts of handwritten assembly.
Does rust let you inline assembly like GCC made a defacto part of c? GCC-rust probbaly will eventually.
The Rust inline assembly macro is actually one of its widely praised features: of course, it's not a massively commonly used feature but when it is used, developers seem to pretty uniformly find it to be extremely nice to work with.
That has been my experience as well.
