As a distributed software developer, I have found debuggers less useful these days. If I need a debugger, it probably means I don't really know the code that I am working on.
Good IDEs with good static analysis, good unit test/integration test/e2e test coverage, a true understanding of the code base before changing it, all these avoid most bugs.
When the production hits a bug, good monitoring and logging can help root-causing. It is extremely difficult to debug and reproduce a bug in a distributed environment. Many bugs I have root-caused are purely based on monitoring and logging then show the proof with mind-execution of the code.

If you're working in a large legacy system where it's not feasible to fully know the code you're working on, I find that debuggers both help me find bugs quicker and improve my understanding of the code.
