An exponential growth is a simple doubling. One becomes two becomes four.

Two-thirds of all growth takes place in cities because, by simple fact of population density, our urban spaces are perfect innovation labs. The modern metropolis is jam-packed. People are living atop one another; their ideas are as well.

People need to understand how exponential technologies are impacting the business landscape. They need to do some future-casting and look at how industries are evolving and being transformed.

Once we start believing that the apocalypse is coming, the amygdala goes on high alert, filtering out most anything that says otherwise.

If you stop and think about it, the form of propulsion used today hasn't changed in over a thousand years... since the invention of fireworks by the Chinese.

If anyone has seen success and failure on a global stage, it's my friend Steve Forbes.
