Why Too Much Efficiency Makes Us Fragile with Olivier Hamant | TGS 230

(Conversation recorded on July 28th, 2026)

For decades, modern civilization has treated efficiency as an unquestioned good: the leaner, faster, and more optimized anything is – from supply chains to your morning routine – the better. But emerging systems science argues that this obsession with performance is actually making humanity more brittle. What if the over-optimization baked into our economies, our agriculture, our institutions, and even our own bodies is at the root of our shared predicament, and how can nature’s intelligence show us a different way?

In this episode, Nate is joined by biologist and biophysicist Olivier Hamant to explore why living systems prioritize robustness over performance, and what that means for a civilization built almost entirely in the opposite direction. Olivier distinguishes performance (efficacy plus efficiency) from robustness (the capacity to remain stable and viable despite fluctuation), and he points out that nature rarely selects for the most efficient organism; it selects for the most adaptable one. Together, Nate and Olivier also trace how cheap, abundant energy allowed human societies to substitute the "safety net" of resource abundance for the safety net that living systems actually rely on: diversity, redundancy, and cooperation. As the twenty-first century moves from an era of stable averages into an era of volatility and standard deviation, Olivier argues that the path forward likely isn't degrowth or continued growth, but a third way: economies and institutions designed to be robust and adaptable to risk, rather than avoid it.

What wisdom have we forgotten for the sake of maximizing material output and efficiency? How has our search for optimization affected our quality of life, and what do we risk by continuing down this same path? Most importantly, could balancing our focus on performance and robustness be the key to reframing our relationship with the entire Earth, bringing more stability, rest, and meaning to our lives?

About Olivier Hamant:

Olivier Hamant is a French biologist and biophysicist whose work combines plant science and civilizational thought. He serves as Director of Research at the French National Research Institute for Agriculture, Food and Environment, teaches at the École Normale Supérieure de Lyon, and directs the Institut Michel Serres – an interdisciplinary institute focused on ecological transition.

Hamant’s work is centralized around the idea that modern civilization has confused “performance” with “fitness” by prizing efficiency/optimization/specialization/maximum output. This is in direct contrast to most living systems, which rarely optimize for these characteristics – instead, living systems survive because they are robust, or able to maintain their identity despite unpredictable disturbances.
