I recently moved teams so that I could use Go exclusively. It's often been said that Go solves the problems Google developers have, and it's 110% true. It's much easier to get things working, and it's much easier to write things like Protocol Buffers. But the key for me is that Go isn't fun in the sense of "wow, I'm so smart that I managed to one line this thing", it's fun in the "wow I read this code and I can understand what's happening and hack on it to do something else."
I've worked on teams with monolithic Java code, and it's nigh-on impossible to understand what's happening and where you are in the logic flow. I don't have that problem in Go. I even delve into the standard libraries to see how the original Go devs did something, and I both understand it and think it looks like code I would have written too. I never get that feeling from any other language, where I feel like the standard libs are written by hyper-intelligent aliens.
When I exclaimed this internally, I got the sarky comment "It's almost as if the things Go leaves out makes it easier". And that's the core of it. Would I like generics? Sure; I do miss map(). But that's it.
Go is opinionated. People that don't like Go don't share the opinion. That's OK. It's taken me a long time to realize there is no One True Language that can do everything (it was soon after steveklabnik said something along the lines of "I don't know why you'd want to write a web app in Rust"). Once you get there, you won't hate Go anymore, nor indeed any other language.
Apart from C++. Screw that ;)
