because someone wrote it with self-righteousness

Usually a call sign of someone who hasn’t been really entrenched with bad code to understand their foolishness in comparison.

I’ve only seen people hold that idea if :

1. New and amateurish, I give them a chance cuz they might learn. But let them learn.
2. Someone who’s only ever worked in maybe two places for very long lengths of time, given way too much power too early, people threw around ‘genius’ too eagerly and these people guard their code like a watch dog likely because it’s so fragile a simple ‘()’ in a string will bust everything . No one else can work on it and the only way you can fix it is the moment they leave. They will not learn. You can only hope the eye of Sauron will stop looking in your direction.
