The point is I wouldn't hire any wedding photographer who was also offering to shoot video unless he had dedicated stills and video shooters with him/her.
Why, when you can theoretically shoot the whole thing in 4K video and then just pull printable stills from the video footage.
Dilbert set up the scenario as 'say we're both wedding photographers'. Not videographers, not both…photographers.
When you start to base your counter-arguments on trivial semantics, then you're grasping at straws.
