I am not sure your definition of upgrade, but it is definitely a downgrade in terms of features even comparing it to Java. It has lean environment that makes it more attractive to systems programming and the CSP (channels, go routines etc.) make it great for concurrency. The trouble starts when you are shifting from systems projects to business logic projects. This is where Java runs circles around Go (or for that matter several other languages/environments). I wish Go had similar type system like OCaml. https://functionwhatwhat.com/go%E2%80%99s-type-system-is-an-embarrassment/ https://functionwhatwhat.com/go%E2%80%99s-type-system-is-an-... If I would like to teach something smart to software engineers I use OCaml, if I want to teach how simple things can achieve a lot I use Go. (They gonna end up programming in Java or Python anyways :)) )
