Elon Musk has spent his career turning improbable ideas into companies that reshape the world. To some, the entrepreneur behind Tesla and SpaceX is an engineering genius whose ambitions have transformed electric cars and space travel. To others, his politics and extraordinary influence raise serious questions about the future he is building. Either way, the world’s first trillionaire is betting Tesla’s future on AI and humanoid robots, and SpaceX’s on life beyond Earth.

In this season’s debut episode, Walter asks Musk about DOGE regrets, why he believes robots will solve America’s national debt, and the dark politics that have consumed his own platform, X. Along the way, Musk shares why living in a simulation demands that we all be less boring. A candid conversation about the imagination, drive and contradictions of a man determined to turn his vision into our future.

Interview taped August 6, 2026.

In the four years since the book’s publication, CRISPR has revolutionized the world of medical treatments and possibilities. But our world has changed drastically, too. As AI’s impact grows, U.S scientists are facing funding cuts like never before. For our final episode, we bring you a live conversation between Walter Isaacson and Jennifer Doudna at the New Orleans Book Festival. In her own words, you’ll hear Doudna explain how CRISPR blossomed from an idea to a phenomenon, and the challenges scientists faces in this politically fraught moment.

As the gene editing field kept growing, so did the dangers. Back in 2018, Jennifer Doudna received an email from a Chinese scientist claiming that he had genetically edited two twin babies. The news reverberated across the world and made Doudna and her colleagues urgently consider the implications of what their discovery could mean for humanity. 

Walter Isaacson sits down with Evan and tells him why the field has always been ripe with ethical questions, and how the COVID-19 pandemic pushed researchers to recalibrate their priorities.

Jennifer Doudna thought she had won the race. She thought she had beaten out all scientific competitors when she and her co-author had shocked the world with their groundbreaking technology for gene editing. But turned out, the race had just gotten fiercer. 

Walter Isaacson sits down with Evan to talk about how one of the most cutthroat scientific competitions in biotech got started around one goal — making CRISPR work for humans, and getting the credit for it.

Back in the 1990s, a young microbiologist in Alicante, Spain became obsessed with a strange pattern he observed in the genes of tiny organisms — a series of inexplicable clusters. And he wasn’t alone. All around the world, a network of scientists were growing curious as to what these genetic knots could be and all of their potential functions. Their curiosity would prove to be the foundation for a history altering discovery: the ability to edit our genetic code.

Earlier this year, when the world learned the news of baby KJ successfully undergoing the first personalized genetic treatment, it represented a milestone for researchers and patients. But behind this scientific feat there’s the story of the technology that made it possible, CRISPR, and one of the key pioneers behind it — Jennifer Doudna. 

Evan sits down with Walter Isaacson to understand how Doudna’s upbringing in Hilo, Hawaii influenced her trajectory as a gene editing scientist. And how the history of gene editing might have started with understanding DNA, but soon after, it became clear the real secret lay with its underrated sibling molecule, RNA.

In this final episode of our series, host Evan Ratliff and biographer Walter Isaacson discuss Benjamin Franklin's remarkable late-in-life achievements-- from his last anonymous essay, to the way he empowered George Washington, to his evolution on slavery, to the beautiful way Philadelphia mourned its favorite son... oh, and they discuss Ben Franklin's favorite magic trick, too!

After retiring at the age of 42, Ben Franklin immersed himself in politics, taking on enormous diplomatic challenges on behalf of Pennsylvania and the colonies. In this episode, we dive into Franklin the talented statesman-- a man who emerged from his mission in England with a taste for revenge, charmed the French into supporting a burgeoning nation, and somehow found time to get involved in every revolutionary tract-- from Common Sense to the Constitution... in between playing chess in the bathtub!

Few people remember that Benjamin Franklin was America’s wealthiest self-made man. After being denied a formal education and then indentured to his own brother, he launched America's first media empire. But while Franklin could be a ruthless businessman, he was out for more than himself—he knew his success was predicated on a strong middle class, a new, American idea. So he started civic ventures like fire departments, street sweepers, and public libraries. But it wasn't until he became a postmaster that he realized why the colonies needed to band together as a nation.

From writing under pen names in the newspaper as a teenager, to the Poor Richard maxims we all know, to the autobiography he created to show the path toward American virtues, Ben Franklin literally wrote the books on what it means to be American. But how close was the real Ben Franklin to the character he created?
