Logging changes the timing of code making it nearly useless for debugging problems of a concurrent nature. It also falls down when systems cannot afford the overhead of printing all trace data (see: video games), or when embedded platforms have no reasonable TTY to send log data to. A debugger is just a tool and to dismiss a tool as being pointless for all people is ridiculous. Being familiar with all the tools at your disposal as a software developer is never a bad thing.
