Oh, don't mistake my comment for favorable opinion. I only wrote a few hundred lines of Go in my life. It worked well for the particular problem I was solving, but I'm really more of a C/C++ guy.
The problem with lisps is that you need to know lisp, and relatively few people do. It also requires a different approach to program design. It may or may not be a better approach, but the fact is, that's not what most people are trained for.
In contrast, go is imperative through and through, and its syntax is similar enough to C that people find it easy to adapt to it.
The little secret of Lisp is that you can use it pretty much as an imperative language, even though it also enables functional programming. The main barrier is that Lisp is taught as a functional programming language, and many believe that this is the only way you should use it.
