I think there is a part of criticism on Go which are not relevant. The language has been designed to be "simple" and it do the job.
The latest posts on Go were only for the Karma, re-post, no new elements, no fair statements.
To answer to your question, I will say it will take you time to understand and to be productive with Rust.
But, please stop, Go and Rust can't be compared, they don't have the same goal in mind.
