Here's an interesting article that highlights the Earth's natural signals -- cells that communicate to one another and organize to ensure their very survival. 

Scientists have figured out how to quantify that data, which is amazing by itself. And now they can compare it to the amount of digital signals created by the internet. It should be no shock that some are predicting the world's digital signals to outpace the natural world in less than a century. 

If there's anything I've learned about the digital world in the last 25 years or so it's that it WILL grow faster than we predict, often in ways we never expected.
