Mostly agree except for code-gen --- definitely not so in the real world! I'd say most Gophers on the whole at a minimum don't mind it, and many either outright ---or eventually--- embrace it.
Depends on the nature and purpose(s) of the Go code-base but for many, it's as natural and idiomatic as is the extensive use of the macro preprocessor for many-perhaps-most grown, matured, "non-trivial" C code-bases. (Just fewer pitfalls in exchange for a bit more set-up effort.)
Elixir is close to my ideal though I like static types and a better community around libs would be nice.
The good side to it being simple to understand and maintain is that you won't pay a lot of debt if you're adding it to your stack.
There isn't a single language that fits all use case perfectly anyway, so we'd have to just go to the "best tool for the job" approach in the meantime.
Care to extend upon why you don't feel go is a good fit for other programming?
People like go for its minimalist approach. Not in the sense that you don't have a lot of code to write, but more in the sense that you are in control of everything that happens, and that you can read an understand every part of your codebase.
ORMs , code gen, magic wrappers, etc is something that people in that community just hate.
