There's a right way and a wrong way to talk to someone about their death. The right way involves making eye contact, making sure that they can hear you, and if they are comfortable with it, holding their hand.
The wrong way involves doing none of those things, because you are talking to them via a shitty Skype connection on wheels.
Technology has a huge role to play in healthcare. It's invaluable in diagnosis and treatment. In the long run it'll probably put a lot of people who do those kind of things out of work. But it should not be used to replace the empathic, emotional aspects of healthcare. If anything, the labour efficiencies generated by technology ought to increase the resources put into empathy -- not be used to eliminate it.
