We're building an artificial intelligence-powered dystopia, one click at a time, says techno-sociologist Zeynep Tufekci. In an eye-opening talk, Tufekci explains how the same algorithms companies like Facebook, Google and Amazon use to get you to click on ads are also used to organize your access to political and social information.

Scared of superintelligent AI? You should be, says neuroscientist and philosopher Sam Harris -- and not just in some theoretical way. We're going to build superhuman machines, says Harris, but we haven't yet grappled with the politics and ethics of how best to contain and manage them.

Artificial intelligence is getting smarter by leaps and bounds -- within this century, research suggests, a computer AI could be as 'smart' as a human being. And then, says Nick Bostrom, it will overtake us: 'Machine intelligence is the last invention that humanity will ever need to make.'

Shohini Ghose wants us to get excited about quantum computers, which operate using an entirely different logic than classical computing. She explains the basics and explores what makes quantum computing so powerful.

Dario Gil uses a deck of cards to explain the principles of quantum computing and its transformative power.

Quantum physicist Nicole Yunger Halpern explores how quantum technologies could transform energy, computing, and data security, including quantum-resistant encryption to protect against future threats.

Bill Gates unveils his vision for the world's energy future, describing the need for 'miracles' to avoid planetary catastrophe and explaining why he's backing a dramatically different type of nuclear reactor. The essential goal? Zero carbon emissions globally by 2050.

What's the key to using alternative energy, like solar and wind? Storage -- so we can have power on tap even when the sun's not out and the wind's not blowing. In this accessible talk, Donald Sadoway takes to the blackboard to show us the future of large-scale batteries.

Chemical engineer Jennifer Wilcox previews technology to scrub carbon from the air, using chemical reactions that capture and reuse CO2 at a vast scale.
