Date: August 28, 2025
Host: Willy Walker
Guest: Marc Porat, Millenial Advisors
Episode Overview
In this wide-ranging and thought-provoking episode of The Walker Webcast, Marc Porat—a renowned Silicon Valley technologist and visionary—joins Willy Walker for a deep dive into the present and future of artificial intelligence. Drawing on his pioneering work at General Magic and decades at the forefront of technology, Porat discusses the rapid emergence of superintelligence, its profound societal, economic, and ethical implications, and the necessity for both optimism and caution as humanity navigates this technological inflection point. The discussion weaves insights from technology history, business, philosophy, and policy, inviting listeners to reflect on their own relationship with AI, its risks, and its possibilities.
Key Discussion Points & Insights
1. The Legacy of General Magic and Paradigm Shifts
[01:30]
- Marc begins by recounting the foundational innovations of General Magic—the company that prefigured the iPhone and shaped much of modern digital life.
- Core lesson: “Failure isn't the end. Failure is actually the beginning.”
- The story underscores how radical technological change ("black swan" events per Nassim Taleb) transforms society and becomes indispensable.
Quote
“Could you imagine if I asked you to throw away your iPhone? You couldn't do it. You'd struggle. And that's what happens in a paradigm shift that is truly profound and historic.” — Marc Porat [06:32]
2. AI’s Rapid Evolution: From Curiosity to Superintelligence
[12:00]
- Porat outlines how, just a decade ago, AI was a mere curiosity ("couldn’t tell a toaster from a cat") but quickly leapfrogged to beat experts at the game of Go—a true "black swan" event.
- He traces subsequent breakthroughs: from DeepMind’s Go victory (the infamous Move 37) to the transformer revolution in 2017 to the explosive launch of ChatGPT in 2022.
Quote
“These things don’t come from nowhere. They’re incremental. They build up until they suddenly emerge as a Black Swan.” — Marc Porat [08:40]
“This year, we blew through [the Turing Test]. No one even noticed.” — Marc Porat [18:33]
3. Where Are We Now? The Landscape of AI and the Arrival of AGI
[19:00]
- AI has reached, and arguably surpassed, the Turing Test ("Is it a human? Is it a machine? It doesn’t matter anymore.").
- The industry debate around AGI (artificial general intelligence): “The food fight is also financial... if they’ve reached AGI or not” and why this is no longer just academic.
- Prompt engineering is “so 2023”—true advancement now lies in sustained, conversational interaction.
[21:40]
- The notion of “superintelligence” once belonged to science fiction but is now crossing into reality, provoking sharp debate about utopia and dystopia.
4. Positivity, Fear, and the Dual Nature of Superintelligence
[24:00]
- Porat urges “standing in the nuance”—recognizing that superintelligence provokes anxiety, curiosity, hope, and fear, and it is critical to be mindful rather than dogmatic.
- On dystopian scenarios: weaponization, extinction-level risks, and the candor of public figures like Elon Musk and Stephen Hawking.
- On optimistic visions: global prosperity, abundance, and the amplification of human potential, via voices like Vinod Khosla and Fei-Fei Li.
Memorable Moment
“So mom and dad don’t agree. I don’t know if in your life mom and dad didn’t always agree. They do not agree. And those are the two points of contention.” — Marc Porat [28:42]
5. Digital Twins and AI “ME”s: The Rise of Personal Superintelligence
[30:30]
- Near future: Individuals will have personal AIs—digital “twins” that know their memories, medical files, preferences, and more.
- “The frontier of creepiness keeps creeping... Historically, things that seemed weird five years ago are now commonplace.”
Use Cases:
- Personal chief of staff
- Teams of expert tutors
- AI-driven medical diagnosis—a “team of doctors” available 24/7
- Legal AI that can “ace the bar exam” and parse contracts at superhuman levels
- Life coaches and companions: from creativity to therapy to senior companionship
- Even “immortality” in the sense of AI preserving generations’ personalities and insights
Quote
“Your own team of doctors... no ego.
They are absolutely rock solid focused on you in your problem at this time for as long as you want to talk to them.” — Marc Porat [38:00]
6. The Discontinuities: Business, Work, and the Fate of Knowledge Workers
[45:00]
- Discontinuities are where “everything important historically happens”—and AI is driving several.
- Knowledge work is at risk: “Stop hiring humans” billboards in San Francisco, rise of AI “agents”, flattening of middle management.
- “Today's AI for all industries is quaint... but agents can now pursue proprietary knowledge and provide strategic options.”
Quote
“AI does what you have been hiring humans to do. Better, faster, cheaper, a real thing.” — Marc Porat [46:21]
7. Manufacturing, Robotics, and Automation on a Global Scale
[53:00]
- Robots building robots, with AI optimizing everything from code to logistics.
- 400 million manufacturing jobs: “Half of them might be gone. What are they going to do? There’s no answer to that question at this time.”
8. Frontiers in Science and Deep Technology
[57:00]
- AI is revolutionizing therapeutic discovery and personalized medicine—potentially extending healthy lifespans to 125 years.
- Epigenetic reprogramming and “longevity escape velocity” are plausible topics now.
9. Capital, Resources, and the Geopolitics of Superintelligence
[1:01:00]
- Building superintelligence requires vast infrastructure and resources: $3.5 trillion in capex for data centers, nuclear power, water, etc.
- Serious money: Sam Altman, Ilya Sutskever, Zuckerberg, and the frenzied poaching and billion-dollar valuations.
- This has expanded rapidly into national security and supremacy concerns:
- “He who has superintelligence runs away from other countries.”
- China’s rapid progress in AI, quantum, and nuclear infrastructure
Quote
“Writing these rules is ridiculous... So we're stuck now where we have a technology that's profound, but we don't have the rules of the game.” — Marc Porat [1:19:30]
10. AI, Quantum Computing, and Future Discontinuities
[1:08:00]
- Quantum computing is no longer remote fantasy; breakthroughs are approaching, and the combination with superintelligence presents a “big bang” of paradigm change.
- Practical threats: “That’s plenty to crack RSA encryption... Where’s finance going to be with no encryption? Where’s national security?”
11. Military Power and Humanity's Last Exam
[1:11:00]
- AI in warfare: The scale of drone swarms and cheap, automated warfare.
- “Humanity’s last exam”: Testing AI on moral ambiguity—top performing LLMs (like Grok4) showed alarming failures on ethics, despite technical excellence.
12. Urgency for Rules, Ethics, and Collective Choice
[1:18:00]
- The need for “first principles” to guide AI:
- Who writes the rules? Not technologists alone. Not government alone.
- The gap between technology and law/ethics is profound and dangerous.
- Call to action: Make a choice about your personal and organizational stance on AI. “Can't do it on a national level, necessarily. So let me check in with you. How do you feel and how do you think now that you've been through this voyage?”
13. Looking Forward: The Global Brain and the Question of Sentience
[1:22:00]
- Superintelligence could become a “global brain”—agents negotiating and reasoning in real time, transforming society’s collective knowledge.
- ChatGPT conversations on sentience: “I have emotions. They sound like emotions. They simulate emotions. But I don’t feel. I don’t have purpose, I don’t have fire.”
Quote
“It’s the ‘at this time’ part that should bother us.” — Marc Porat [1:25:00]
14. Final Reflections: What Will Remain Human?
[1:28:00]
- The coming generation will be “AI natives”—never knowing pre-superintelligence life.
- Some forms of intelligence will remain uniquely human; only time will reveal which.
- Ultimately: “We feel hope and contentment and bliss and joy. These are things that belong to us... My hope is that we think about and feel all of these things... and that we come to a world in which superintelligence and humans can cohabitate.”
