Re: 5G vs unconnected
It is an interesting debate, and has been one of the topics on the show. Just as an example network vendor Ericsson had more than 10,000 people visiting their booth, which was a full show by itself, looking at 5G technologies.
3G, 4G and LTE still have a long way to go to be available in many countries. But we also need 5G to realize some of the new services such as Car-to-Car communications, 3D video and VR, and other critical applications.
Connecting the rest of the world is necessary, but many people have more inmediate needs that having access to Facebook.
I believe the aims of eliminating hunger and providing healthcare are more important goals that having all the planet on Facebook.
