> I get he's ranting about imprecise terminology, but really, what does this knowledge gain the end user?

Reminds me of an experience I had in college. I was working phones over the summer at a call center and had this software developer call in. This was during the runup to Y2K, and I mentioned the "Y2K bug" and he starts ranting about how it's not a bug.

And I'm like, yes I understand it's not technically a bug, but most non-technical people don't know the difference.

I've never understood why people are like this with non-technical folks. If you're having a technical discussion with another technical person, then yes, the distinction absolutely matters. But to non-technical people? Who exactly benefits from that?
