I agree with jart on this. Rust has gained a reputation for overzealous marketing (also called evangelism), and we who like and use Rust should do everything possible to reverse that reputation, by being honest, even to a fault, about known limitations.
Don't get me wrong, I too agree on your sentiment (even though technically it wasn't a Rust's own fault), but I also believe that jart's claim was something else and a comparison with academic paper should be sufficient to show that.
