Growing up, Danielle Walker’s family often convened for big meals prepared by her Italian grandmother, Grandma Marge. Back then, Danielle enjoyed a wide variety of food without restriction; but she began experiencing severe abdominal pain in her 20s that ultimately led her to totally transform her diet—cutting grains, lactose, sugar and more.

As Danielle found relief in this approach—and realized that others with similar ailments could as well—she began compiling her recipes in an online blog called Against All Grain. Before long, the self-taught chef became a bestselling cookbook author, more recently branching out with her own product lines and cooking courses.

This week on How I Built This Lab, Danielle talks with Guy about being an ‘accidental entrepreneur’ as she chronicles her journey to building a multifaceted business centered around healthy eating. Plus, Danielle shares her advice for other creators looking to build an audience and discusses food’s potential to help millions suffering from autoimmune diseases.

As one of the most successful creators on YouTube, Mark Rober doesn’t see what he does as a business. Instead, it’s a way to celebrate science in the most joyful way possible. While working as an engineer at NASA, he made his YouTube debut with a tutorial on how to make a gory Halloween costume with two iPads and a lot of duct tape. Over time, his videos became more elaborate, including a belly flop into a pool full of Jello, and a demo of a glitter-fart bomb to get revenge on porch pirates. Within a few years, Mark was teaching online science classes and selling subscription boxes for kids. Today, his YouTube channel has 5.5 billion views, 48 million subscribers…and–astonishingly, given that audience–less than 150 videos.

In other words: an artificial agent that can do all the kinds of cognitive tasks that people can typically do, and possibly more...

Now as the Chief AGI Scientist and a co-founder of Google DeepMind, he stands by that prediction and is calling on the world to prepare.

This week on How I Built This Lab, Shane’s path to becoming an early AI expert and the work he and his team are doing to prepare for the technological revolution ahead.

Best friends Rhett McLaughlin and Link Neal started out as “comedians for Christ,” and grew their partnership into one of the most successful YouTube platforms in existence. During college they created silly videos and songs for Christian events, and later built a following on YouTube before most people knew what it was. After struggling to find stardom in Hollywood, they continued to build a presence on YouTube: sampling punishingly hot peppers, writing ear-wormy songs about random things, showing off glasses that turned the world upside down. Nowadays, their entertainment company, Mythical, reports over 75 million subscribers and 25 billion lifetime views.

Best-selling author and economics professor Renée Mauborgne thinks that too many entrepreneurs focus on the wrong things—consumed with making their companies outperform one another as they fight for a greater share of a crowded market space. But what if entrepreneurs focused on creating new markets instead of fighting over old ones?

This week on How I Built This Lab, Renée shares insights from her Blue Ocean Strategy series to help founders crack open new opportunities. Plus, what is non-disruptive innovation and can it offset job displacement in the age of AI?

Whole30 began as a dietary experiment: For 30 days, Melissa Urban went without grains, dairy, legumes, alcohol and added sugar. She was trying to address several health problems, and the results were so extraordinary that she decided to share the diet with others.

What followed was a blog, a series of seminars, a best-selling book and eventually a wide-ranging wellness brand that’s helped millions of people identify the best diet for their own body. But in 2015, Melissa had to rethink everything—even her own name—when she split up with her husband and business partner, Dallas Hartwig. She retained ownership of the business, and today, the “Whole30 Approved” logo appears on a range of brands, from La Croix water to Chipotle salad bowls.

The popular science fiction idea of beaming someone instantly to another location was part of David Nussbaum’s inspiration to design a “holoportation box.” His company, Proto, invented a device the size of a telephone booth that projects a hologram-type image so realistic it appears someone is standing inside...

This week on How I Built This Lab, how Proto’s technology is used today to virtually transport professors, doctors, speakers, and celebrities to classrooms, hospitals, and events around the world. But in the future, David believes Proto’s technology will end up in everyone’s living room—and will transform the way we communicate with each other.
