Most of the time, when someone says "It's complicated" in a response to a simple solution that is offered, the real problem is that they're complicating it.
"It's complicated" is usually an excuse for not simplifying and correcting a problem.
It's a way to excuse leaving a problem alive.
It's basically saying "It'll be hard to fix, and we'll have to stop doing something that carries technical debt, so we're just going to leave it all fucked up".
If something's complicated, uncomplicate it.
@AskTheDevil this comes across as very dismissive. "It's complicated" can mean that. It can also mean that you don't know the nuance of the person's experience and they're not interested in sharing that nuance. It can mean that they're exhausted by the situation & don't want to talk about it with you. It can mean the things you're suggesting won't work but they know you're going to argue with them, so they'd just rather not. It can be a nonconfrontational way to say it's none of your business.
@VenessaG I apologize for allowing my speech to come across as dismissive. I see your point.
I hope I was able to clarify somewhat, and correct my failed speech?
@AskTheDevil I do appreciate you hearing me out and being willing to have a dialogue about it.
