Rust is for the lowest level code which is not assembly, with all the performance tricks, but that should be secure.
Rust is expensive to develop - if you can afford to use a GC, you should use a GC.
So people want to rewrite all the world's C and C++ to rust, for security. But people are less passionate about rewriting all the world's python into go for performance.
This has not been the case for many people using Rust, including myself. Once you learn the language, there is no "cost" to use it. In fact, the compiler simplifies much of the mental overhead when dealing with concurrency, sharing data, mutability, etc... Sure the compiler has some strict rules, but it's not expensive to develop in by any means.
I would also say Rust is in a sense higher-level than Go in terms of expressiveness and abstractions.
I like GCs, but I wouldn't make such a blanket statement. Manual memory management as implemented in Rust also eliminates data races at compile time, which are in fact the last item listed in the original article.
