The list of speakers consisted of some of the brightest minds and spirits in our world whose stories illuminate and ignite our beliefs of what is possible. The group included whistleblower/patriot/sometimes enemy of the state (pick one) Edward Snowden whose talk shed light on the right to data privacy, surveillance and internet freedom. Fashion model Geena Rocero told her tale of rebirth in becoming a woman after being identified as a male for the first half of her life. Astronaut Chris Hadfield recounted his harrowing and hilarious tale of going blind in space. Bill and Melinda Gates talked with TED curator Chris Anderson about their life after having made billions, and during which they’ve spent giving away that very same money. The collection of content and talent was inspiring, educational, and eye-opening, and allowed us to re-examine the fear that we commonly feel when change and the unknown are thrust upon us.

One of the most moving presentations was delivered by Hugh Herr, the head of the MIT Media Lab’s Biomechatronics Center for Extreme Bionics. His work in fusing biomechanics and microprocessors has made mobility easier for himself, a double leg amputee and for countless people around the world. One of those people is ballroom dancer Adrienne Haslet-Davis who lost her leg in the 2013 Boston Marathon bombing. Herr’s work has resulted in prosthetic technology that allowed Haslet-Davis to perform for the first time since her injury in front of the TED 2014 audience. Watch the amazing talk and performance below.
