You mean the executives that sit in meeting rooms with video conferencing equipment and a couple of other people? Talking to one or more other meeting rooms filled with other groups of people?

Of course you have a certain point when the company is small and in one location and no need to talk to external parties often. It's far from universal. And everyone with their own mic and camera is way better than the dude that's always too far from the mic and only the people that are in his location can understand and converse with him etc.
