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.'

MIT grad student Joy Buolamwini explains how biased algorithms can lead to unfair outcomes and shares her work on auditing AI systems for ethical implications in everyday technologies like facial recognition.

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.

Leo Kouwenhoven discusses the challenges and potential of building practical quantum computers.

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

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.
