Why do we have to fly?

I am confused. So often I witness these conversations at customer's and after all these years I'm still puzzled. I'm not saying that we need to stop all face-to-face meetings, not at all.
Nonetheless, we sometimes move too easily when we can be more productive and efficient by connecting via video. Technology has changed, now we can have a good meeting experience, some real interaction, not just a sequence of "What?", "Can you repeat please?", "Who's talking?". 
We have the technology!!!
It's not prohibitive anymore to implement a decent video collaboration system, far better than consumer-ish solutions such as Skype or Hangouts. Even in that case it might be an acceptable solution, while sub-par and limitating. Probably that's the reason video has yet to be widely accepted: in most user's mind, Skype is still the reference for video conversations. Movies show Skype-like conversations in outstanding quality and we expect real-life experience to be the same.That's not the case, but it doesn't mean we can't get it with other tools. 
Because we can.
