So when is animation.....not animation?

Ok, so I was talking to this guy at Badminton today who I'd never met before. I explined to him I was studying animation and what I was doing and stuff. And he said the strangest thing to me when I explained that I was drawing animation.

"You can do animation...without computers?" Seriously. Has it got to that point, where all aniamtion at least seems to be CG, and people dont think about 2D anymore as animation?

Very strange...
