The evidence is largely in, what remains is a discussion around root causes, and what -- if anything -- can be done.
Personally, the topic became particularly urgent when I saw a recent documentary ("Chasing Ice") which features stunning time-lapse photography of massive glaciers and ice sheets melting before your very eyes.
Seeing is believing. Our world is changing, faster than we thought.
In many ways, the most recent IDC Digital Universe study provides clear evidence that our world is also changing from a physical one to a digital one, and much faster than we previously thought. In addition to attempting to quantify and forecast how much information we collectively generate and consume, it highlights particular "big picture" topics of concern to many.
Many of us now live our lives primarily in a digital world. We work digitally, socialize digitally and spend our off hours digitally.
Our children are being raised and educated largely in a digital world. Businesses are in hot pursuit to re-invent themselves in this digital world, followed closely by public sector. "IRL" (in real life) has started to become the exception rather than the norm.
Our world is changing, faster than we thought.
But unlike climate change, our digital world is mostly good for all involved -- a major leap forward for us as a society: richer lives, better answers to social problems, and -- above all -- easier access to the information riches the world now has to offer. Like all transformations, it presents its own unique challenge.
In many regards, I see the IDC study as useful and important -- it measures the "digital footprint" of this unprecedented transformation. And, as in past years, there's much more insight to be gained other than just appreciating some really big numbers.
