Oh I hate the idea of physical media going away. I just worry that various entertainment industries really want this to happen, and will do whatever it takes to force us to only use digital versions under their control. And something like WhatsApp or FaceTime replacing phone calls seems very plausible. That's the other thing right there; you don't need a traditional phone to call people anymore, so there's a good chance people will call others in messaging apps rather than via standard calls.
