The superpower of a debugger is watchpoints and inspecting data structures. No need to laboriously write out a rendering of the internal state of a program when you can pop open its objects and look at their state in the debugger. Breakpoints, step-in, step-over, step-out, all good things. That said, a debugger is not a substitute for robust tracing/logging. By the time a program gets mature, it will probably end up being instrumented to generate nice-looking, useful traces. Often, that will be good enough to debug in the future. I just don't understand people who will actively avoid using a tool. Like, I don't get it. Do you trim your lawn with scissors?
