My professional history is with C, C++, C#, Fortran, even years of Object Pascal in Delphi back in the day.
In no universe does Go feel like it's a "bit backwards", and I think you're trying to speak for a group without their input.
Indeed, an implementation I regularly use now is high performance algorithms in C++ (the Intel vectorizing compiler is superb) to function libraries, Go/cgo as the extremely efficient, very easy to write and maintain orchestration/manager.
I speak for the ones that got interested into Go as a mix of C and Oberon, even tried to initially contribute and went away as the language became a kind of Java 1.0.
The ones addressed by Rob Pike on his post about C++ developers.
