Very true. Go has proven big success outside Google. So many people here argue here that Go is not good enough else why Google keep using other languages even now. But same people argue in Apple/Swift case "of course Apple need not rewrite all perfectly working applications in Swift". But somehow Google has to do to prove language is fine.
