It depends on the language. I've used debuggers in java, much less in c++, and hardly in go. I feel there is not much of a need in go for debugging, writing good tests and the occasional log/print statement do fine.

Java, often having more complicated structures and layers (more due to the culture, one could write more go-like simpler java as well) is more reliant on debugging. More dynamic (less predictable) languages such as python even more.
