Why you would need 5G?

> In the new world, you will take control of your health data — and decide who you share that data with.

This made me chuckle, because it's utterly unrelated to 5G and entirely a function of laws, terms-of-service, and consumer power. But anyway,

'5G' right now is an idealized target of big-picture requirements like more bandwidth, efficiency, coverage, 'more of everything'. You'll need more actual fiber in the ground to get there [1][2]. But once we do, anything that vomits massive amount of data on the wire is a possible use-case.

Networked cars? Sure. Sensor data, healthcare, IoT? Live video, VR, AR? Yeah. Broadcast, even though we've had non-packet-switched-broadcast-networks-for-a-100-years? Why not, we have capacity!
