Episodes

What would happen if we upload our brains to computers? | Robin Hanson  

Meet the "ems" -- machines that emulate human brains and can think, feel and work just like the brains they're copied from. Futurist and social scientist Robin Hanson describes a possible future when ems take over the global economy, running on superfast computers and copying themselves to multitask, leaving humans with only one choice: to retire, forever. Glimpse a strange future as Hanson describes what could happen if robots ruled the earth.

What moral decisions should driverless cars make? | Iyad Rahwan  

Should your driverless car kill you if it means saving five pedestrians? In this primer on the social dilemmas of driverless cars, Iyad Rahwan explores how the technology will challenge our morality and explains his work collecting data from real people on the ethical trade-offs we're willing (and not willing) to make.

How AI can enhance our memory, work and social lives | Tom Gruber  

How smart can our machines make us? Tom Gruber, co-creator of Siri, wants to make "humanistic AI" that augments and collaborates with us instead of competing with (or replacing) us. He shares his vision for a future where AI helps us achieve superhuman performance in perception, creativity and cognitive function -- from turbocharging our design skills to helping us remember everything we've ever read and the name of everyone we've ever met. "We are in the middle of a renaissance in AI," Gruber says. "Every time a machine gets smarter, we get smarter."

How computers learn to recognize objects instantly | Joseph Redmon  

Ten years ago, researchers thought that getting a computer to tell the difference between a cat and a dog would be almost impossible. Today, computer vision systems do it with greater than 99 percent accuracy. How? Joseph Redmon works on the YOLO (You Only Look Once) system, an open-source method of object detection that can identify objects in images and video -- from zebras to stop signs -- with lightning-quick speed. In a remarkable live demo, Redmon shows off this important step forward for applications like self-driving cars, robotics and even cancer detection.

Meet Spot, the robot dog that can run, hop and open doors | Marc Raibert  

That science fiction future where robots can do what people and animals do may be closer than you think. Marc Raibert, founder of Boston Dynamics, is developing advanced robots that can gallop like a cheetah, negotiate 10 inches of snow, walk upright on two legs and even open doors and deliver packages. Join Raibert for a live demo of SpotMini, a nimble robot that maps the space around it, handles objects, climbs stairs -- and could soon be helping you out around the house.

The human insights missing from big data | Tricia Wang  

Why do so many companies make bad decisions, even with access to unprecedented amounts of data? With stories from Nokia to Netflix to the oracles of ancient Greece, Tricia Wang demystifies big data and identifies its pitfalls, suggesting that we focus instead on "thick data" -- precious, unquantifiable insights from actual people -- to make the right business decisions and thrive in the unknown.

Why our screens make us less happy | Adam Alter  

What are our screens and devices doing to us? Psychologist Adam Alter studies how much time screens steal from us and how they're getting away with it. He shares why all those hours you spend staring at your smartphone, tablet or computer might be making you miserable -- and what you can do about it.

Why we need to imagine different futures | Anab Jain  

Anab Jain brings the future to life, creating experiences where people can touch, see and feel the potential of the world we're creating. Do we want a world where intelligent machines patrol our streets, for instance, or where our genetic heritage determines our health care? Jain's projects show why it's important to fight for the world we want. Catch a glimpse of possible futures in this eye-opening talk.

How I built a jet suit | Richard Browning  

We've all dreamed of flying -- but for Richard Browning, flight is an obsession. He's built an Iron Man-like suit that leans on an elegant collaboration of mind, body and technology, bringing science fiction dreams a little closer to reality. Learn more about the trial and error process behind his invention and take flight with Browning in an unforgettable demo.

3 principles for creating safer AI | Stuart Russell  

How can we harness the power of superintelligent AI while also preventing the catastrophe of robotic takeover? As we move closer toward creating all-knowing machines, AI pioneer Stuart Russell is working on something a bit different: robots with uncertainty. Hear his vision for human-compatible AI that can solve problems using common sense, altruism and other human values.

The future we're building -- and boring | Elon Musk  

Elon Musk discusses his new project digging tunnels under LA, the latest from Tesla and SpaceX and his motivation for building a future on Mars in conversation with TED's Head Curator, Chris Anderson.

How I'm fighting bias in algorithms | Joy Buolamwini  

MIT grad student Joy Buolamwini was working with facial analysis software when she noticed a problem: the software didn't detect her face -- because the people who coded the algorithm hadn't taught it to identify a broad range of skin tones and facial structures. Now she's on a mission to fight bias in machine learning, a phenomenon she calls the "coded gaze." It's an eye-opening talk about the need for accountability in coding ... as algorithms take over more and more aspects of our lives.

Don't fear superintelligent AI | Grady Booch  

New tech spawns new anxieties, says scientist and philosopher Grady Booch, but we don't need to be afraid an all-powerful, unfeeling AI. Booch allays our worst (sci-fi induced) fears about superintelligent computers by explaining how we'll teach, not program, them to share our human values. Rather than worry about an unlikely existential threat, he urges us to consider how artificial intelligence will enhance human life.

The incredible inventions of intuitive AI | Maurice Conti  

What do you get when you give a design tool a digital nervous system? Computers that improve our ability to think and imagine, and robotic systems that come up with (and build) radical new designs for bridges, cars, drones and much more -- all by themselves. Take a tour of the Augmented Age with futurist Maurice Conti and preview a time when robots and humans will work side-by-side to accomplish things neither could do alone.

Help discover ancient ruins -- before it's too late | Sarah Parcak  

Sarah Parcak uses satellites orbiting hundreds of miles above Earth to uncover hidden ancient treasures buried beneath our feet. There's a lot to discover; in the Egyptian Delta alone, Parcak estimates we've excavated less than a thousandth of one percent of what's out there. Now, with the 2016 TED Prize and an infectious enthusiasm for archaeology, she's developed an online platform called GlobalXplorer that enables anyone with an internet connection to discover unknown sites and protect what remains of our shared human inheritance.

Where is cybercrime really coming from? | Caleb Barlow  

Cybercrime netted a whopping $450 billion in profits last year, with 2 billion records lost or stolen worldwide. Security expert Caleb Barlow calls out the insufficiency of our current strategies to protect our data. His solution? We need to respond to cybercrime with the same collective effort as we apply to a health care crisis, sharing timely information on who is infected and how the disease is spreading. If we're not sharing, he says, then we're part of the problem.

How online abuse of women has spiraled out of control | Ashley Judd  

Enough with online hate speech, sexual harassment and threats of violence against women and marginalized groups. It's time to take the global crisis of online abuse seriously. In this searching, powerful talk, Ashley Judd recounts her ongoing experience of being terrorized on social media for her unwavering activism and calls on citizens of the internet, the tech community, law enforcement and legislators to recognize the offline harm of online harassment.

Meet the inventor of the electronic spreadsheet | Dan Bricklin  

Dan Bricklin changed the world forever when he codeveloped VisiCalc, the first electronic spreadsheet and grandfather of programs you probably use every day like Microsoft Excel and Google Sheets. Join the software engineer and computing legend as he explores the tangled web of first jobs, daydreams and homework problems that led to his transformational invention.

How AI can bring on a second Industrial Revolution | Kevin Kelly  

"The actual path of a raindrop as it goes down the valley is unpredictable, but the general direction is inevitable," says digital visionary Kevin Kelly -- and technology is much the same, driven by patterns that are surprising but inevitable. Over the next 20 years, he says, our penchant for making things smarter and smarter will have a profound impact on nearly everything we do. Kelly explores three trends in AI we need to understand in order to embrace it and steer its development. "The most popular AI product 20 years from now that everyone uses has not been invented yet," Kelly says. "That means that you're not late."
