I haven't used Rust extensively, more Go for sure. But it seems to me that Go was aiming for simplicity more than being a true innovation. It's basically a compiled Python with type annotations and unfortunately a GC to spoil it all.

Rust was aiming at innovating and advancing the PL space with meaning. I can't say looking back the time I invested with Go was well-spent.

Rust is probably worth the effort if you have the need for what it offers. It just requires more out of you than Go does.
