The old unix philosophy of "print nothing on success" looks crazy until you start trying to build pipes and shell scripts that use multiple tools internally. Also very quickly makes it clear why stdout and stderr are separate

It never felt crazy to me, with the exception that are many situations where having progress and diagnostic information (usually opt-in) made sense.

I guess it comes down to a choice of printing out only relevant information. I hate noisy crap, like LaTeX.

Also becomes rapidly apparent that most modern tooling takes an extremely liberal view of logging levels. The fact that you’ve successfully processed a file is not INFO, that’s DEBUG.
