You can now do everything electronically instead of printing it.

So these are dollar bills right here being printed, either physically or electronically.

Therefore, we try to persuade people not to have cash, to have money electronically transferred.

They communicate electronically constantly, and they have protocols and checklists for how they handle everything (Laughter)

And face to face groups are much smarter than groups that communicate electronically, because 90 percent of our communication is non verbal.

And now comes the technology into it, because with this new way of communicating electronically these kids can communicate with each other around the world.

So they would send the message to contact, they'd set an appointment, they'd send out a short summary electronically, they'd have a conversation, and follow up.

And we're going to focus just for visualisation purposes, on them doing it phyisically, they could also do it electronically, but we're just going to focus on the physical.

Alan Turing showed that a very simple model was enough to capture everything that a mechanical computer could do, whether it was a human computer or a modern computer that operates electronically, like we think of today.

But now that we're switching to merging medical data, making it available electronically, we can crowd source that information, and now as a physician, I can access my patients' data from wherever I am just through my mobile device.

Because if we can do that, if we can actually just collect the data electronically, digitally, from the very beginning, we can just put a shortcut right through that whole process of typing, of having somebody type that stuff into the computer.

Now the tragedy about climate change is that we can solve it with a simple, honest approach of a gradually rising carbon fee collected from fossil fuel companies and distributed 100 percent electronically every month to all legal residents on a per capita basis, with the government not keeping one dime.

If we get into a mode in which everything is handled electronically, and your only identification is some little plastic thing you stick into the machinery, then I can image that they want to get that settled up with your bank account, just right now, and put it through all the checks and that would require a network.
