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.'

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.

How can architects build a new world of sustainable beauty? By learning from nature. Michael Pawlyn describes three habits of nature that could transform architecture and society: radical resource efficiency, closed loops, and drawing energy from the sun.

Boyan Slat shares his bold plan to clean up the Great Pacific Garbage Patch using innovative technology to harness ocean currents.

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.

There's a lot of talk about the need to regulate AI, but physicist Max Tegmark says we need to think bigger: what if we could design AI to make our lives better in every way? Tegmark explores the exciting possibilities of life with superintelligent machines -- and how we can ensure that the benefits of AI are shared fairly.

As we expect more from technology, do we expect less from each other? Sherry Turkle studies how our devices and online personas are redefining human connection and communication -- and asks us to think deeply about the new kinds of connection we want to have.

Adam Alter shares his research on how time spent looking at screens is increasing -- and how it's affecting our well-being and happiness.

A handful of people working at a handful of tech companies steer the thoughts of billions of people every day, from running elections to what we see and think. Tristan Harris argues that technology is hijacking our attention and what we can do about it.
