You're not doing yourself a favor when you point out "but they can't do arithmetic!" as if anyone says otherwise. Yes, we all know they can't do arithmetic, and that's just how they work.

I feel like I'm saying "this hammer is so cool, it's made driving nails a breeze" and people go "but it can't screw screws in! Why won't anyone talk about that! Hammers really aren't all they're cracked up to be".
