It was successful due to massive amount of money spent by Google. Because there were languages that are much better suited for what Go was designed for. To name a few: Erlang (concurrency that is better than Go's, "channels" and types on par with Go with Dialyzer), Haskell (thread concurrency better than Erlang's, channels, transaction memory, etc and types well beyond Go) and many others. Go was successful despite mistakes.
