Go is an incremental improvement over the C++ ecosystem without all the legacy baggage.

Go has little to do with C++, it throws away many useful features (generics, const-correctness, RAII). Also, where C++ encourages reuse of existing C libraries, Go 'penalizes' it by making C calls expensive and placing restrictions on interaction with C (e.g. you cannot store pointer to Go data structures). There are reasons for doing this, but all these things make Go pretty much unacceptable for people who are in C++'s niche.

If Go can be compared to any language with traction, it's the later Pascal family of languages (Oberon) and Java pre-generics. It even makes some of the same mistakes (first no generics, then probably retrofitted generics).
