When you need to make a decision, you might turn to AI for advice. But what happens when you let algorithms decide more and more things for you? Computational social scientist Sandra Matz reveals how AI models limit what you see, discover and try, subtly flattening what makes you unique. Hear her tips for how to use AI to fuel your curiosity and expand your world instead.

What’s the best way to make a project more playful? Game designer Eric Zimmerman has a counterintuitive suggestion: a few good rules.

Animals are communicating — but what are they saying? And can we talk back? Marine biologist David Gruber introduces Project CETI: a team of scientists, linguists and AI specialists hoping to decode sperm whale language. Using noninvasive robots and a machine-learning algorithm to collect and analyze millions of sperm whale vocalizations known as coda, the team aims to demystify the communication structures and dialects of these majestic creatures — and possibly even crack the interspecies communication code. (This ambitious plan is a part of the Audacious Project, TED’s initiative to inspire and fund global change.)
