I've never found that Go is not fun to write. On the contrary... Go is pretty refreshing with its simplicity. I found myself to be immensely productive writing Go.

For sure! Why is Google throwing their own language under the bus? They're literally saying in their article Go isn't the easiest language to write but that doesn't matter because its the best for maintaining a project. I also don't buy that readability and writeability are always being traded off.
