Going deep: The Battle Between Horizontal and Vertical Work

In this episode of 'The Knowledge,' host David Elikwu dives into the dichotomy between horizontal and vertical models of engaging with the world. Using Donald Knuth's drastic life decision to quit email in 1990 as a starting point, David explores the philosophical implications of being either on top of things or at the bottom. The episode draws on historical and contemporary examples, from ancient philosophies to modern neuroscience, and includes insights from notable figures like Isaac Newton and Leonardo da Vinci. David emphasises the value of deep, focused work versus the appeal of staying broadly informed and connected, ultimately challenging listeners to identify the one thing so compelling to them that it is worth digging deep for.
