Great list of why one can love and hate Go. I really did enjoy writing it but you never get the sense that you can be truly certain your code is robust because of subtle behaviour around nil.
I guess as a corollary, Go really rewards writing the dumbest code possible. No advanced type shenanigans, no overuse of interfaces, no complex composition of types. Then you will end up with a very fast, resource light system that just runs forever.
You could say the same thing about any language. Writing "dumb" code is easier to understand especially in the small. But Go with function that take functions and return functions, channels and generics, can quickly look as complex as other languages.
