When Tristan Harris co-founded the Center for Humane Technology in 2018, he was trying to educate tech leaders and policymakers about the harms of social media. But today, he’s sounding the alarm about a different technology — one that he says could pose an existential threat to the entire world … Artificial intelligence. This week on How I Built This Lab: the first of a two-episode series in whic...

In 2002, John MacFarlane and his co-founders began tinkering on what was then an ambitious idea: create a new way to enjoy music throughout the home, without wires.

Mike Cessario came up with the idea for a viral water brand by asking himself “What is the dumbest possible idea we could have?” His answer was Liquid Death: an aluminum can of water that looks like a cross between beer and poison.

Those two identities came into conflict in 2018 when negotiating a contract renewal with her shoe sponsor, Nike.  Ultimately, Allyson broke ties with Nike because the new contract presented a significant pay cut and lacked adequate maternal protections. After struggling to find a new shoe sp...

This week on How I Built This Lab, N...

When Hernan Lopez founded Wondery in 2016, podcasts were just starting to go mainstream. Five years later, his team had scored a number of hit shows and sold to Amazon for a reported $300 million.
