Can you provide an example of Rust users making overly-complex systems? Rust is a systems language, and systems themselves have intrinsic complexity that language designers must either choose to ignore or tackle. Scripting languages have the luxury of removing complexity by ignoring systems concerns so you don't have to care that your language is, say, copying strings around like a maniac behind your back. But somebody has to compete at the bottom of the stack, and while you can still seek ergonomic wins there's an enormous amount of essential complexity that can't be abstracted away.
