I've read both the submission and the articles that exist inside that Quora link you posted and I am still not convinced. IMO what makes a language better is end products and not features. When Rust becomes stable, its community will produce great software but I don't think all of the rest languages you mentioned have produced (or will do) better software than Docker, Kubernetes, OpenShift, etcd, btcd, and a ton of other Go software.

It's useful to distinguish between "the language" and "the tool". Some programming languages are terrible from a language design perspective (PHP, JavaScript, MATLAB), but they still have great tools (IDEs, build tools, package managers) and libraries to help programmers create good and interesting software.
The tooling around Go is good but not that great. What makes Go better than all those languages is that it's more complete: a language that does not get into your feet, good tooling, great community, and more. IMHO saying that a language is better or worse based only on "the language" is silly.
