Legendary Inventor Danny Hillis — Solving the Impossible (Plus Kevin Kelly)

Here are the top 10 key takeaways from Tim Ferriss's conversation with legendary inventor Danny Hillis, offering profound insights into innovation, learning, and long-term thinking.

1. The process of invention is widely misunderstood

Danny Hillis believes that the process of invention is often misinterpreted. The inventor's contribution is actually a small piece of a much larger puzzle. Society creates the preconditions for invention, and once those preconditions are in place, it becomes a matter of putting together puzzle pieces that are often overlooked because they're viewed by different people across different disciplines.

Hillis illustrates this with his experience building the first parallel computers. At the time, many experts believed parallel computing was impossible due to "Amdoll's law." However, Hillis recognized that the human brain worked in parallel despite having slower components than transistors. All the necessary preconditions existed - he could design CMOS chips, compiler technology was ready, and digital television cameras were becoming available. He simply connected these existing pieces when others wouldn't due to the prevailing belief that it couldn't be done.

2. Learning through association with extraordinary people

Hillis has developed a distinctive approach to learning: find the smartest people in a field and spend time with them. This strategy has enabled him to acquire knowledge in diverse domains throughout his career. He doesn't necessarily know things others don't, but he often possesses a unique combination of knowledge from various fields.

His approach is illustrated by two remarkable examples. First, as a young man wanting to work with AI pioneer Marvin Minsky at MIT, Hillis couldn't access the secured AI lab. He studied their research proposals in the building's lobby, developed a programming solution addressing one of their needs, and eventually secured entry. Second, when starting his parallel computing company, he asked Nobel physicist Richard Feynman if any students might be interested in working with him. Feynman offered himself instead, showing up and declaring "Richard Feynman reporting for duty, sir." These associations with brilliant thinkers profoundly shaped his development and career trajectory.

3. The entanglement of nature and technology

Hillis observes that nature and technology, once distinctly separate domains, are becoming increasingly entangled. Traditionally, technology was something humans designed, understood, and controlled, while nature remained mysterious and complex. Now these boundaries are blurring in both directions.

Natural elements like the atmosphere, our genes, minds, and bodies are becoming technological artifacts we can manipulate. Simultaneously, technological systems like the internet and AI models have grown so complex that nobody fully understands them - they're more like natural phenomena we interact with through "magic incantations" without comprehending their inner workings. This convergence suggests the distinction between natural and artificial may eventually dissolve, with both representing different aspects of the same underlying reality.

4. Artificial intelligence as human intelligence on artificial substrate

Hillis offers a unique perspective on current AI systems, describing them not as truly artificial intelligence but as "human intelligence on an artificial substrate." He explains this through his "Songs of Eden" concept - a story about how human intelligence evolved through co-evolution between primates and the memes they created and shared.

In his view, today's AI models are substrates on which human intelligence (in the form of data, culture, and language) can live outside human bodies. While current systems are primarily imitative, imitation is the first stage of intelligence development, as seen in child development. Hillis believes we're just beginning to move beyond the imitation stage as these systems demonstrate basic reasoning capabilities. This perspective suggests a fundamental shift in how we conceptualize AI systems - not as separate artificial minds but as extensions of collective human intelligence.

AI systems will likely continue evolving capabilities beyond imitation. However, Hillis maintains that what we have now isn't truly "artificial intelligence" but rather human intelligence being expressed through a different medium. This framing challenges mainstream narratives about AI as an independent form of intelligence.

5. Embracing both technical and artistic perspectives

During his time at Disney as a "Disney Fellow," Hillis gained what he calls a "second education" in the artistic approach to problem-solving, which complemented his engineering background. Engineers focus on functional diagrams and technical specifications, while artists concentrate on emotional experiences and storytelling.

Hillis discovered the importance of storytelling in design when he saw how Disney approached theme parks. Rather than viewing them as architectural projects, they designed parks as stories - creating coherent emotional experiences with beginnings, middles, and ends. This approach dramatically influenced his later work, particularly the 10,000 Year Clock. Initially focusing on mechanical problems like winding mechanisms and materials, he realized the most critical factor in the clock's longevity would be how people experienced and related to it.

This integration of artistic thinking led to specific design choices like having the clock display the time of the last visitor rather than the current time. When visitors wind the clock, it catches up to the present, creating a personal connection. Visitors can also take home rubbings of the date as souvenirs. These experiential elements, inspired by his Disney education, became more important than the technical solutions.

6. Three criteria for choosing meaningful projects

Hillis employs three specific criteria when deciding which projects to pursue at his invention company, Applied Invention. First, one of the senior partners must be genuinely excited about the project, typically because it has potential for significant positive impact or involves fascinating technology. This ensures emotional investment in the work.

Second, partners not emotionally invested must evaluate whether the project makes financial sense. This could mean either limiting potential losses or having a reasonable chance at substantial returns. This criterion adds practical discipline that Hillis admits was missing in his early career ventures, when he would pursue projects before they made financial sense.

The third and most challenging criterion is what Hillis calls the "non-redundancy criterion" - they only take on projects that wouldn't happen otherwise. This means identifying unique reasons why a valuable project isn't being pursued by others and determining if they bring something special to the table. This approach ensures they focus their limited resources on making differences that wouldn't otherwise occur.

7. A systems view for transforming agriculture

Hillis has recently become interested in agriculture after growing food on his New Hampshire farm during COVID and realizing how much better it tasted than store-bought produce. This led him to analyze the entire food system, identifying its inefficiencies and unsustainability. His systems thinking approach focuses on changing the entire framework rather than optimizing individual problems within it.

The current agricultural system relies on shipping food great distances, breeding varieties for durability rather than flavor, and exploiting low-wage labor. Hillis believes we need a comprehensive redesign that brings food production closer to consumption. This would require simultaneous changes to greenhouse architecture, labor practices, plant breeding, soil microbiomes, and more.

What distinguishes Hillis's approach is looking beyond "point solutions" to identify a new equilibrium where many changes work together. He notes that most commercial opportunities focus on optimizing individual components, but transformative change requires addressing the system holistically. This systems view allows him to see potential solutions that others miss because they're looking at isolated elements rather than the interconnected whole.

8. Questioning the nature of cause and effect

One of Hillis's most provocative views is that cause and effect don't exist in the way we typically think. He believes causality is simply a story we tell because, as social creatures, we're inclined to personify nature and identify agents that cause change. This mental framework is useful but ultimately just a conceptual tool rather than a fundamental truth about reality.

He illustrates this with Newton's equation F=MA. We typically interpret this as "force causes mass to accelerate," but one could just as easily rewrite it as A=F/M and say "mass is caused by force acting on acceleration." The direction of causality exists in our narrative, not in the equation itself. Our brains evolved to look for causes and effects, making this framework intuitively appealing, but Hillis suggests reality itself doesn't contain these relationships.

This isn't merely a philosophical position - it has practical implications for Hillis. He views digital computing as "the ultimate fantasy of putting together causes and effects," and suggests that quantum computing challenges our cause-effect intuitions. He speculates that future AI systems might think without relying on this conceptual framework, potentially accessing modes of understanding beyond human limitations.

9. Long-term thinking and sustainable impact

Hillis places immense value on creating impact that lasts beyond his lifetime. This philosophy materializes most visibly in the 10,000 Year Clock project - a massive timepiece built inside a West Texas mountain designed to tick for ten millennia. The clock serves as a tangible symbol of long-term thinking, encouraging people to consider humanity's development over tens of thousands of years.

When deciding how to spend his time, Hillis asks, "Will this make a difference over how much time?" He prefers projects whose impacts extend far into the future, even after his death. He contrasts this approach with organizations that prioritize measurable short-term impacts, noting they may miss opportunities with significant long-term value. He cites Claude Shannon's invention of the bit as an example - its full impact is only becoming apparent decades after Shannon's lifetime.

Interestingly, Hillis finds satisfaction in the fact that the 10,000 Year Clock has taken on a life as a story, with many people believing it's mythical rather than real. To him, the idea and story have more lasting power than any physical artifact. This reflects his belief that stories and ideas ultimately create the most enduring impact on human consciousness and behavior.

10. Embracing childlike curiosity and learning without fear

When asked about his superpower, Hillis suggests it might be "not being afraid to learn new stuff." He believes this quality - approaching unfamiliar subjects with fearless curiosity - is something we're all born with but often lose as we grow older. Society frequently discourages this natural exploratory instinct, but Hillis was fortunate to have people around him who didn't "beat it out of him."

His childhood experiences likely contributed to this mindset. As the son of an epidemiologist, Hillis lived wherever hepatitis outbreaks occurred - often places experiencing war and famine. This constant exposure to different cultures and environments fostered his ability to shift perspectives and adapt to new situations. This trait was later described by his child as being a "mindshifter" - someone who easily adopts different mindsets and views things from multiple perspectives.

This fearless approach to learning has driven Hillis's remarkably diverse career spanning parallel computing, Disney Imagineering, clock-building, cybersecurity, and agriculture. Rather than limiting himself to a single domain of expertise, he continually ventures into unfamiliar territory. His willingness to acknowledge what he doesn't understand - rather than pretending expertise - allows him to learn continuously and connect ideas across disciplines in innovative ways.
