Sure, I agree completely. But they're both systems languages. I write systems software, and Go already has barely any traction in the broader software community (outside of Hacker News...), so I have to choose what's easy to learn and has a reasonable level of support.
Languages always succeed based on support (documentation, community, tooling)--not features.
I brought Go up here because it stands the best chance of inheriting the role that C and C++ occupied for systems software, and which Python is also taking over. That's why it was created, so developers could have a statically-typed systems language that wasn't C or C++ or Python or Java, since all of those were unsuitable in various tasks for one reason or another.
