Honoring Klaus Truemper
A Renaissance Human in the Age of AI Hype
This post is a tribute to Klaus Truemper, a spectacular human who passed away in July 2025 at the age of 83. Klaus was a Professor Emeritus of Computer Science at the University of Texas at Dallas, a thoughtfully intelligent human who bridged logic and compassion, and a true renaissance man who met life with curiosity, vitality, and kindness. He died doing what he loved: solo-adventuring in his plane.
Klaus and I shared a deep interest in understanding and explaining models of natural and artificial intelligence for non-expert audiences. His recent research and writing was focused on the history of mathematics, brain science, and AI. His intellectual rigor was matched by his relational generosity. His humility and vibrancy in life brought joy, insight, and affirmation to those around him.
In 2021, Klaus published Magic, Error, and Terror: How Models in Our Brain Succeed and Fail. The book left a lasting impression on me. His ideas were simple yet expansive, blending insights from neuroscience, emotion, and cognitive behavioral therapy (CBT). He challenged the academic silos of discrete, logic-heavy computer science by discussing how flawed subconscious models and decision-making patterns could be updated through introspective and therapeutic practices. I found this perspective radical and deeply resonant with my own healing journey.
In this book, he also critiqued the flawed logic of model-dependent realism, warning of its widespread harms. In a poignant section, he wrote:
"If we were to ask dolphins, whales, and elephants about the wholesale destruction of the earth's lands, oceans, and mass extinction of animals... they would say that the earth suffers from a pandemic infestation by humans."
His ecological sensitivity was matched by a rigorous critique of how flaws in understanding the structure, function and behaviors of human mental models can lead to devastating consequences. His writing style reflects a unique capacity to use creative narratives to express complex concepts using simple examples that highlight deep truths. His books on intelligence form a series that highlight state of the art understandings across domains of physics, neuroscience, cognitive science, philosophy and culture.
The concepts are covered from multiple layered perspectives across different example situations and use Wittgenstein’s Language-games as a method to inspect the nature of language to express human experience, and abstract concepts like free will.
Since I have a passion for such topics, it will be a joy to present his ideas in the upcoming posts. There are some topics where our views slightly diverge, but that is the beauty of his work because he welcomed such explorations as part of the learning process.
He closed the book with a reflection that continues to inspire awe:
"The trip across the landscape of brain science has been like a dream visit to a new and wonderful land. The journey has clarified a number of issues for us and has filled us with humility: What a wondrous world we live in!"
We first connected through a department email discussion in 2022, where I shared my interest in scale-free models of resonance energy patterns for intelligence and holistic systems modeling. Our first in-person meeting was at a faculty holiday lunch in December 2022. I spoke about my trauma healing journey and experimental approach to grounding self-trust and intuition with adaptive decision-making capacity by inverting beliefs and re-learning to co-regulate my nervous system. Klaus was deeply engaged. The discussion, which began over lunch, continued for hours in the parking lot, drawing in others. It was a moment of rare intellectual and emotional convergence.
Shortly after that meeting, I phased off antidepressants, with a strong support network, and a family-systems therapist, to more fully experience and regulate emotions. Klaus’ kind support during this transition was invaluable.
For nearly a decade, I had been teaching at UT Dallas, developing curriculum for artists and game designers that use a lens of creative modeling, information dynamics and simulation. My PhD research had been disrupted by complex trauma and the COVID-19 pandemic, and I struggled to find resonance within shifting academic structures. Klaus’ encouragement during this time was deeply meaningful. We exchanged texts, book recommendations, family and nature photos, and conversations about intelligence and modeling.
Our lived experiences contrasted and complemented each other in unexpected ways. Klaus had hyperphantasia—vivid mental imagery—while I live with aphantasia, a blank inner canvas. His aerial photos of Jenny Lake, wildflowers, and the view from Signal Mountain echoed the photos and videos I had shared after a skiing across Jenny Lake finding solitude in winter. These exchanges were a poetic and symbolic meeting of opposites: summer and winter, sky and snow, mental image and photograph.
We both felt a profound connection to the fragile ecosystem of Teton National Park. In future posts, I plan to explore its history and significance, especially in light of current environmental threats and policy rollbacks. These shared landscapes became part of our shared language.
Klaus' intellectual contributions remain under-appreciated. His 2023 book, Artificial Intelligence: Why AI Projects Succeed and Fail, introduces the "Neuroprocess Hypothesis" and critiques the misleading simplicity of the "web of facts" paradigm. He provides a lucid integration of neuroscience and AI, helping readers grasp how human cognition and artificial systems diverge and overlap. I highly recommend all of his books about AI to anyone seeking to understand intelligence in a nuanced, humane, and rigorous way. I had read several in kindle format, but I recently purchased and received the paperback versions, and so I am enjoying rereading them as a way to rediscover their magic so that I can share their deep wisdom in future posts. Klaus presented some of these ideas at UTD in May 2024, using diagrams that I plan to adapt and share in future posts.
What stood out about Klaus was his humility, kindness, curiosity, and understanding of the necessity of being a life-long learner. Reading his books or blogs about flying, it is clear that he understood the value of cultivating habits of mindfulness and learning from reflections on personal experience and those of others by paying close attention to the information we encounter.
He had a rare ability to express these insights with clarity and humor. During that 2+ hour lecture in May 2024, his sense of joy and humor was captivating, inviting the audience into a spacious and meaningful reflection on the implications of AI and human intelligence. The insights he shared in that lecture are ones I plan to adapt and share in future posts. His work will continue to inform my thinking and the development of visual models I’m designing to teach systems thinking and embodied intelligence.
I miss Klaus deeply. But I am grateful that his words, images, and ideas remain. In honoring his memory, I hope to carry forward the spirit of thoughtful inquiry, joy, and adventurous compassion that he embodied so well.
Thank you so much for this thoughtful and moving tribute to my father. 🙏🏻
Great article Karen thanks for sharing this and future updates!
