The WORST episodes of TED Talks

Every episode of TED Talks ever, ranked from worst to best by thousands of votes from fans of the show. The worst episodes of TED Talks!

TED is a nonprofit devoted to Ideas Worth Spreading. It started out (in 1984) as a conference bringing together people from three worlds: Technology, Entertainment, Design. TEDTalks began as a simple attempt to share what happens at TED with the world. Under the moniker "ideas worth spreading," talks were released online. They rapidly attracted a global audience in the millions. Indeed, the reaction was so enthusiastic that the entire TED website has been reengineered around TEDTalks, with the goal of giving everyone on-demand access to the world's most inspiring voices.

#1 - Gary Liu: The rapid growth of the Chinese internet -- and where it's headed

Season 2018 - Episode 207 - Aired 7/9/2018

The Chinese internet has grown at a staggering pace — it now has more users than the combined populations of the US, UK, Russia, Germany, France and Canada. Even with its imperfections, the lives of once-forgotten populations have been irrevocably elevated because of it, says South China Morning Post CEO Gary Liu. In a fascinating talk, Liu details how the tech industry in China has developed — from the innovative, like AI-optimized train travel, to the dystopian, like a social credit rating that both rewards and restricts citizens.

Season 2018 - Episode 194 - Aired 6/25/2018

There's a creeping sameness in many of our newest urban buildings and streetscapes, says architect Vishaan Chakrabarti. And this physical homogeneity — the result of regulations, mass production, safety issues and cost considerations, among other factors — has blanketed our planet in a social and psychological homogeneity, too. In this visionary talk, Chakrabarti calls for a return to designing magnetic, lyrical cities that embody their local cultures and adapt to the needs of our changing world and climate.

#3 - Paul Rucker: The symbols of systemic racism -- and how to take away their power

Season 2018 - Episode 195 - Aired 6/26/2018

Multidisciplinary artist and TED Fellow Paul Rucker is unstitching the legacy of systemic racism in the United States. A collector of artifacts connected to the history of slavery — from branding irons and shackles to postcards depicting lynchings — Rucker couldn't find an undamaged Ku Klux Klan robe for his collection, so he began making his own. The result: striking garments in non-traditional fabrics like kente cloth, camouflage and silk that confront the normalization of systemic racism in the US. "If we as a people collectively look at these objects and realize that they are part of our history, we can find a way to where they have no more power over us," Rucker says. (This talk contains graphic images.)

Season 2018 - Episode 197 - Aired 6/27/2018

In October 2017, astrobiologist Karen J. Meech got the call every astronomer waits for: NASA had spotted the very first visitor from another star system. The interstellar comet — a half-mile-long object eventually named `Oumuamua, from the Hawaiian for "scout" or "messenger" — raised intriguing questions: Was it a chunk of rocky debris from a new star system, shredded material from a supernova explosion, evidence of alien technology or something else altogether? In this riveting talk, Meech tells the story of how her team raced against the clock to find answers about this unexpected gift from afar.

The United States accounts for five percent of the world's population but consumes almost 70 percent of the total global opioid supply, creating an epidemic that has resulted in tens of thousands of deaths each year. How did we get here, and what can we do about it? In this personal talk, Travis Rieder recounts the painful, often-hidden struggle of opioid withdrawal and reveals how doctors who are quick to prescribe (and overprescribe) opioids aren't equipped with the tools to eventually get people off the meds.

Season 2018 - Episode 193 - Aired 6/22/2018

Writer and artist James Bridle uncovers a dark, strange corner of the internet, where unknown people or groups on YouTube hack the brains of young children in return for advertising revenue. From "surprise egg" reveals and the "Finger Family Song" to algorithmically created mashups of familiar cartoon characters in violent situations, these videos exploit and terrify young minds — and they tell us something about where our increasingly data-driven world is headed. "We need to stop thinking about technology as a solution to all of our problems, but think of it as a guide to what those problems actually are, so we can start thinking about them properly and start to address them," Bridle says.

There are about a hundred trillion microbes living inside your gut — protecting you from infection, aiding digestion and regulating your immune system.
