> I'm not sure if you must be able to use strace to be productive

You will be productive until whatever runtime/library you are using has a serious bug or performance issue. Then you either use tools like strace or your productivity drops to 0. It is not a matter of marginal or order-of-magnitude productivity differences. You don't "understand stuff" for sentimental reasons, you "understand stuff" because the alternative is your manager has to call in people like me that "understand stuff" and pay them tens of thousands of dollars to fix things that you can't.

> It always puzzled me how people can be comfortable using this kind of stuff.

It's called learning.




Wow nice. I want to do this one day too ;)

> It's called learning.
