For Professor Klaus Schwab, Founder and Executive Chairman of the World Economic Forum, "we stand on the brink of a technological revolution that will fundamentally alter the way we live, work, and relate to one another" - welcome to the Fourth Industrial Revolution.

Young people will be at the heart of this revolution. And it troubles John Green, the best-selling author and vlogger, that we write off "millennials" as a generation of self-obsessed navel-gazers. In fact, even the word "millennial" makes him cringe.

At a time when European leaders discussed how to hold their union together as tensions over the Syrian refugee crisis mounted, the economist Hélène Rey made an impassioned plea against protectionism and populism.

While Europe struggles with its identity, Africa has the chance to build a new one based on clean energy and new technology. That's what the Fourth Industrial Revolution means to Alpha Condé, President of Guinea.

For Mexico's President Enrique Peña Nieto, making the most of digital technology is key. Luckily, the constitution is on his side.

The revolution is rippling through industries, too. For Mary Barra, the CEO and Chairman of General Motors, driving yourself to work in a petrol-fueled car will soon be a thing of the past.

Devin Wenig, CEO of eBay, also expects rapid change. "Imagine a world where you want a red cashmere sweater that is a certain fit, style and length. This is immediately manufactured and on your doorstep in five days. That reality is closer than many believe."

With our latest research showing that women are particularly vulnerable to job losses in the Fourth Industrial Revolution, Anne-Marie Slaughter calls for a total overhaul in the way we work so that both men and women can combine a job and family.

After the hottest year on record, climate change was on the agenda at Davos. Surging temperatures and habitat destruction are causing a new wave of extinction, writes Joel Sartore, photographer and conservationist.
