About this conversation
In this episode, Aidan McCullen interviews Samuel Arbesman, author of Overcomplicated: Technology at the Limits of Comprehension, to explore the hidden complexity of modern technology. As our systems evolve, they become so interconnected and layered that even the experts who built them can’t fully understand how they work.
From unexplained tech failures—like the New York Stock Exchange outage and Toyota’s sudden acceleration issues—to the concept of accretion in system development, this conversation dives deep into why our tools are no longer transparent. Arbesman discusses the limits of human comprehension, the tension between generalists and specialists, and why intellectual humility is essential in the age of AI.
Whether you’re a technologist, leader, innovator, or simply curious about how our digital world functions, this episode will challenge how you think about complexity.
🎙 Hosted by Aidan McCullen, keynote speaker on change and innovation.

Key topics discussed:
Why systemic failures are inevitable—and what to do about it
Why technology is often “overcomplicated” by design
The danger of spaghetti code and legacy systems
How “accretion” shapes complexity in tech
The role of generalists in a specialized world
Understanding vs. navigating systems
This is a must-listen for leaders, technologists, and innovators navigating today’s complex digital ecosystem.
