Rust is placing itself as the replacement of C and C++, not as a scripting language or something at a higher level, so it makes sense to see it from the perspective of someone who would write their engine in C or C++. And note that my comment wasn't dismissive of Rust, it was dismissive of the idea that projects like rg3d can cause gamedevs to turn towards rust. The reasoning is really at the second to last paragraph of my comment ("developers have either already decided what language to use (be it rust or something else) or are not in a position to decide what language to use").
