I haven't tried Go myself and I've been meaning to, but I have spent the last 3 years writing Scala code. Before learning Scala I didn't have any real experience with FP, and I think that was the real learning hurdle for me. Once I learned the FP ideas Scala became my preferred language. I think it's really funny but Java and C# have been becoming more Scala like, and to some extent the latest version of JavaScript are also starting to become Scala like. What I have come to accept is that Scala does take people time to learn, but it's not typically Scala the language, it's the FP aspects of it that are the stumbling blocks.

PS. I also work on a 100k Scala program and can go from clean to compiled in less than 2 minutes, and incremental compiles are extremely fast.
