The problem with C++'s complexity is that you have to remember all of it yourself and if you forget some of it... boom undefined behaviour and elusive runtime bugs! Rust is definitely on the same order of magnitude of complexity, but you don't have to remember it all. Usually if you forget some complex rule and make a mistake, the compiler will tell you. That's not true for unsafe Rust, but you rarely need unsafe Rust. Apart from FFI I have yet to use it at all and I've been writing Rust for years. Async Rust is probably the closest it gets to C++'s "you didn't explicitly co_return in the context of a promise with no return_void? ok carry on but I'm going to crash sometimes! maybe just in release mode, on another OS".
