In this episode of Redefining Tomorrow, Zoltan Istvan joins David Goldsmith for a bold and wide-ranging conversation on transhumanism, the future of humanity, and the role of science and technology in reshaping what it means to be human.

Zoltan brings his perspective as a futurist, author, and political candidate to explore how advancements in artificial intelligence, biotechnology, and human enhancement are challenging long-held assumptions about life, death, and identity. The discussion moves beyond surface-level futurism into the deeper philosophical and societal implications of extending human capability and lifespan.

Together, they examine the tension between technological progress and ethical responsibility, and what it means to consciously design the future of civilization rather than react to it.

• What transhumanism actually means beyond the headlines
• Technology as a force for redefining human limits
• The future of life extension and human enhancement
• Ethics, identity, and the boundaries of being human
• From journalism to futurism: Zoltan’s path
• The role of politics in shaping technological futures
• Fear vs. possibility in emerging science
• Artificial intelligence and human evolution
• Designing the future vs. inheriting it
• Civilization at an inflection point

Zoltan Istvan is a futurist, author, entrepreneur, and political figure known for advancing the global conversation around transhumanism and the role of science and technology in shaping humanity’s future.

With a background as a journalist for National Geographic and a career spanning over 100 countries, Zoltan has explored the intersection of technology, philosophy, and human potential. He is the author of The Transhumanist Wager, a #1 bestseller in philosophy, and has spoken at institutions including the World Bank, World Economic Forum, and UK Parliament.

Zoltan has advised organizations ranging from the U.S. Navy to international governments, and continues to write for major publications such as The New York Times, Newsweek, Vice, and Wired. He is currently running for California Governor in 2026 and remains a leading voice in the movement to rethink human capability, longevity, and the future of civilization.

In this episode of Redefining Tomorrow, Dr. Olivia Ly Lesslar joins David Goldsmith for a deep exploration into the intelligence of the human body, the limits of conventional diagnosis, and the idea that the body is not broken but often trying to communicate.

As an Australian medical doctor working across psychoneuroimmunology, longevity, functional medicine, and complex-condition medicine, Olivia brings a systems-level view of health. She explains why symptoms are not always failures in the body, but signals shaped by environment, history, nervous system state, lifestyle, stress resilience, and evolutionary biology.

Together, David and Olivia explore what happens when medicine becomes too specialized, when patients lose agency, and when diagnosis becomes a label rather than a path to understanding. The conversation moves through the nervous system, placebo and nocebo, chronic illness, environmental toxicity, fertility, stress resilience, and the deeper question of how we learn to listen to the body before assuming it needs to be fixed.

• Why listening may matter more than diagnosis
• The loss of patient agency in modern medicine
• Psychoneuroimmunology and the mind-body feedback loop
• Placebo, nocebo, belief, and biological chemistry
• Stress, eustress, resilience, and the language we use around health
• Why history-taking is becoming a lost medical skill
• How genetics, lifestyle, environment, and behavior interact
• Lactose intolerance, chronic disease, and the misunderstanding of “faults”
• The nervous system’s role in healing and performance
• Fight, flight, rest, digest, and the biology of recovery
• Environmental toxicity, microplastics, food systems, and modern disease
• Sex, safety signals, intimacy, and nervous system regulation
• Evolutionary biology and why ancient survival responses can become maladaptive today
• Why sustainable health may require curiosity, autonomy, and trust in the body

Dr. Olivia Lesslar is an Australian medical doctor internationally recognized for her work in psychoneuroimmunology, longevity, and complex-condition medicine. With formal training in medicine and international relations, she brings an interdisciplinary perspective that bridges neuroscience, immunology, behavioral science, functional medicine, and systems-level thinking.

Often described as a “medical Sherlock Holmes,” Dr. Lesslar is known for her ability to investigate complex, multi-system health conditions that do not fit neatly into conventional diagnostic categories. Her work combines scientific rigor, pattern recognition, clinical intuition, and a patient-centered approach to understanding the deeper roots of chronic and multifactorial illness.

She is Director of Functional and Longevity Medicine at Cingulum Health in Sydney and holds academic appointments at Griffith University’s National Centre for Neuroimmunology and Emerging Diseases and the Geneva College of Longevity Science. Her advisory work spans biotechnology, neurotechnology, longevity medicine, and integrative health organizations across multiple countries.

In this deep and exploratory episode of Redefining Tomorrow, James Arbib joins David Goldsmith for a journey into the roots of civilization, the illusions we’ve inherited, and how they shape the futures we’re building. As co-founder of RethinkX and the Stellar World Initiative, James walks us through thousands of years of societal evolution—from the Neolithic revolution to today’s techno-environmental narratives—and asks us to consider whether we truly understand the systems we’re trying to fix.

They explore why scarcity thinking dominates global policy making, how civilizations have mirrored each other through to modern America, and why rethinking our assumptions—not just our tools—may be the only way forward.

• Rediscovering civilization’s real turning points
• Why yesterday explains today—and tomorrow
• America as just another shade of Summer
• Scarcity, survival, and the growth imperative
• Degrowth and the psychological trap of guilt-based solutions
• How environmental zealotry became systemic and ineffective
• Matter, energy, and information vs. land, labor, and capital
• Competitive advantage and the DNA of societal design
• The illusion of progress and the limits of modern framing
• From history to now: rethinking civilization’s operating system

James Arbib is a visionary thought leader, author, investor, and philanthropist dedicated to exploring how disruptive technologies can address humanity's greatest challenges. As co-founder of RethinkX and the Stellar World Initiative, James brings a unique interdisciplinary perspective that bridges technology, economics, history, and systems thinking.

With a background in history and finance, James moved into environmentalism and disruptive innovation, founding the philanthropic Tellus Mater Foundation to explore solutions for complex global problems. His intellectual journey led him from traditional environmental advocacy to a bold new view: that technological transformation—when deeply understood—offers the most profound opportunities to shape a better future.

He has co-authored Rethinking Humanity and Stellar with Tony Seba and helped lead groundbreaking research on disruptions in transportation, energy, and food systems.
