IMO it's not as good a language as Rust, so I wouldn't learn it for the purposes of making something. However it's very easy to learn (at least to a productive level), so you may as well if you want to.
Just work through go by example and see what you think.
By far the best thing about Go is the tooling. Language itself is eh.
I agree, but if you take away the hard numbers from this (which you should) all you're left with is what we all already knew from experience: fast languages are more energy efficient, C, Rust, Go, Java etc. are fast; Python, Ruby etc. are super slow.
It doesn't add anything at all.
