Humility is a hacker virtue for sure: pride reduce your ability to learn in several ways.

In any case, do not spread this shit.
If you are a hacker there's no reason to marginalize your self just because your curiosity doesn't match a few boring nerds circle-jeriking about infosec or similar personal-marketing bullshit.
