I used to use debugger when I was young - disk space was small, disks were slow and logging was expensive.

Now, some 35 years later, I greatly prefer logs. This way I can compare execution paths of different use cases, I can compare outcomes of my changes, etc. I am not confined to a single point of time with tricky manual control as with debugger, I can see them all.

To old grugs: learning to execute and rewind code in your head is a major superpower. And it works on any codebase.
