I think the issue here is that you're comparing Go to C and Haskell. C is decades old. Haskell was designed to help you write correct programs, rather than simplicity of use or productivity (or that's how I'd characterise it). If you compared Go to C# or Java 8 or Scala, it'd probably look a lot worse. Deployment isn't so difficult that Go has any advantage in my experience: install a JVM on the server, ensure your build system is producing a fat jar, run it. Done. With Capsule you can even make self-executable JARs that have a little shell script attached. Then you can run the program like any other UNIX app. chmod +x and ./execute it. Fully self contained, and can even update itself automatically.
