> Go is not a language focused around individual productivity in any capacity or scope.

I don't know the motivation behind the people developing Go, but I found it very easy and convenient to work with it, almost as easy as with Python sometimes, which is mind-blowing IMO given the static, compiled, strict, etc. nature of Go. So again, don't know whether the guys behind the language were motivated by personal productivity, but they have definitely achieved it.

Though I didn't really try Lisp other than quick tutorials, so I can't make a comparison with that.
