I'm a CS professor teaching some programming courses. I always make an effort to teach my students how to use a debugger and encourage them to use it, because otherwise they will not even try (print debugging comes naturally, while using the debugger requires more effort). I want them to master it so they can make conscious decisions about what to use. Then, when I code myself, I use print debugging like 99.9% of the time :D I have the feeling that, for me, the debugger tends to be not worth the effort. If the bug is very simple, print debugging will do the job fast so the debugger would make me waste time. If the bug is very complex, it can be difficult to know where to set the breakpoints, etc. in the debugger (let alone if there's concurrency involved). There is a middle ground where it can be worth it but for me, it's infrequent enough that it doesn't seem worth the effort to spend time making the decision on whether to use the debugger or not. So I just don't use it except once in a blue moon. I'm aware this can be very personal, though, hence my tries to have my students get some practice with the debugger.
