Google's Go Programming Language Grows Up: Now What?: "So what's Go good for? According to distinguished Google Engineer Rob Pike, the co-designer of the Go programming language, it's designed for "big software."
Pike says Go is best for "large programs written by many developers, growing over time to support networked services in the cloud: in short, server software. Go enables programmers to develop software quickly and maintain and adapt it easily as it grows. It combines the efficiency of traditional compiled languages with the ease of use and expressiveness of scripting languages." (Being a member of the original Bell Labs Unix team, Pike does know a thing or three about systems software.)
