Will truth and reason survive the evolution of artificial intelligence? AI researcher Gary Marcus says no, not if untrustworthy technology continues to be integrated into our lives at such dangerously high speeds. He advocates for an urgent reevaluation of whether we're building reliable systems (or misinformation machines), explores the failures of today's AI and calls for a global, nonprofit organization to regulate the tech for the sake of democracy and our collective future. (Followed by...

In the last few decades, China has gone from technological scarcity to abundance. What sparked this shift? Economist Keyu Jin explores how China has fostered a model of innovation unlike any other and shows why understanding its competitive, collaborative approach could benefit the world -- and perhaps demystify some contradictions.

In an astonishing talk and tech demo, neurotechnologist Conor Russomanno shares his work building brain-computer interfaces that could enable us to control the external world with our minds.
