In this episode, we explore the intricate world of modern technology with Samuel Arbesman, author of Overcomplicated: Technology at the Limits of Comprehension.

Why did the New York Stock Exchange shut down in 2015? What caused Toyota vehicles to accelerate without warning? Samuel reveals how technological "accretion" and interconnected systems create outcomes that even developers, engineers, and executives can't predict.

We discuss:

Why technology often evolves beyond human comprehension
How "spaghetti code" and legacy systems create systemic risk
The biological limits of human understanding
Generalists vs. specialists in innovation
The balance between intellectual humility and progress
How we can better live with—and design—overcomplicated systems

This is a must-listen for leaders, technologists, and innovators navigating today's complex digital ecosystem.

🎙 Hosted by Aidan McCullen, keynote speaker on change and innovation.
