hm I agree on the points made you made on the GoLang -- its design seem to be a regression. (to add another: look at Go's "default-value instead of Null" instead of adding actual null-safety in the type-system like kotlin/swift/scala/typescript/etc.)

Anyway, this blog-post seems to rally for a better eco-system work on Rust part. Being a new language without a rich parent (like Go's "google" or C#/Typescript's "MSFT"), the situation is somewhat understandable.
