Advancements in Metal Printing and Its Impact on Aerospace and Automotive Racing

On this episode of the Crazy Wisdom podcast, I, Stewart Alsop, sat down once again with Aaron Lowry for our third conversation, and it might be the most expansive yet. We touched on the cultural undercurrents of transhumanism, the fragile trust structures behind AI and digital infrastructure, and the potential of 3D printing with metals and geopolymers as a material path forward. Aaron shared insights from his hands-on restoration work, our shared fascination with Amish tech discernment, and how course-correcting digital dependencies can restore sovereignty. We also explored what it means to design for long-term human flourishing in a world dominated by misaligned incentives. For those interested in following Aaron’s work, he's most active on Twitter at @Aaron_Lowry.

Timestamps

00:00 – Stewart welcomes Aaron Lowry back for his third appearance. They open with reflections on cultural shifts post-COVID, the breakdown of trust in institutions, and a growing societal impulse toward individual sovereignty, free speech, and transparency.

05:00 – The conversation moves into the changing political landscape, specifically how narratives around COVID, Trump, and transhumanism have shifted. Aaron introduces the idea that historical events are often misunderstood due to our tendency to segment time, referencing Dan Carlin’s quote, “everything begins in the middle of something else.”

10:00 – They discuss how people experience politics differently now due to the Internet’s global discourse, and how Aaron avoids narrow political binaries in favor of structural and temporal nuance. They explore identity politics, the crumbling of party lines, and the erosion of traditional social anchors.

15:00 – Shifting gears to technology, Aaron shares updates on 3D printing, especially the growing maturity of metal printing and geopolymers. He highlights how these innovations are transforming fields like automotive racing and aerospace, allowing for precise, heat-resistant, custom parts.

20:00 – The focus turns to mechanical literacy and the contrast between abstract digital work and embodied craftsmanship. Stewart shares his current tension between abstract software projects (like automating podcast workflows with AI) and his curiosity about the Amish and Mennonite approach to technology.

25:00 – Aaron introduces the idea of a cultural “core of integrated techne”—technologies that have been refined over time and aligned with human flourishing. He places Amish discernment on a spectrum between Luddite rejection and transhumanist acceleration, emphasizing the value of deliberate integration.

30:00 – The discussion moves to AI again, particularly the concept of building local, private language models that can persistently learn about and serve their user without third-party oversight. Aaron outlines the need for trust, security, and stateful memory to make this vision work.

35:00 – Stewart expresses frustration with the dominance of companies like Google and Facebook, and how owning the Jarvis-like personal assistant experience is critical. Aaron recommends options like GrapheneOS on a Pixel 7 and reflects on the difficulty of securing hardware at the chip level.

40:00 – They explore software development and the problem of hidden dependencies. Aaron explains how digital systems rest on fragile, often invisible material infrastructure and how that fragility is echoed in the complexity of modern software stacks.

45:00 – The concept of “always be reducing dependencies” is expanded. Aaron suggests the real goal is to reduce untrustworthy dependencies and recognize which are worth cultivating. Trust becomes the key variable in any resilient system, digital or material.

50:00 – The final portion dives into incentives. They critique capitalism’s tendency to exploit value rather than build aligned systems. Aaron distinguishes rivalrous games from infinite games and suggests the future depends on building systems that are anti-rivalrous—where ideas compete, not people.

55:00 – They wrap up with reflections on course correction, spiritual orientation, and cultural reintegration. Stewart suggests titling the episode around infinite games, and Aaron shares where listeners can find him online.

Key Insights

1. Transhumanism vs. Techne Integration: Aaron frames the modern moment as a tension between transhumanist enthusiasm and a more grounded relationship to technology, rooted in "techne"—practical wisdom accumulated over time. Rather than rejecting all new developments, he argues for a continuous course correction that aligns emerging technologies with deep human values like truth, goodness, and beauty. The Amish and Mennonite model of communal tech discernment stands out as a countercultural but wise approach—judging tools by their long-term effects on community, rather than novelty or entertainment.
2. 3D Printing as a Material Frontier: While most of the 3D printing world continues to refine filaments and plastic-based systems, Aaron highlights a more exciting trajectory in printed metals and geopolymers. These technologies are maturing rapidly and finding serious application in domains like Formula One, aerospace, and architectural experimentation. His conversations with others pursuing geopolymer 3D printing underscore a resurgence of interest in materially grounded innovation, not just digital abstraction.
3. Digital Infrastructure is Physical: Aaron emphasizes a point often overlooked: that all digital systems rest on physical infrastructure—power grids, servers, cables, switches. These systems are often fragile and loaded with hidden dependencies. Recognizing the material base of digital life brings a greater sense of responsibility and stewardship, rather than treating the internet as some abstract, weightless realm. This shift in awareness invites a more embodied and ecological relationship with our tools.
4. Local AI as a Trustworthy Companion: There’s a compelling vision of a Jarvis-like local AI assistant that is fully private, secure, and persistent. For this to function, it must be disconnected from untrustworthy third-party cloud systems and trained on a personal, context-rich dataset. Aaron sees this as a path toward deeper digital agency: if we want machines that truly serve us, they need to know us intimately—but only in systems we control. Privacy, persistent memory, and alignment to personal values become the bedrock of such a system.
5. Dependencies Shape Power and Trust: A recurring theme is the idea that every system—digital, mechanical, social—relies on a web of dependencies. Many of these are invisible until they fail. Aaron’s mantra, “always be reducing dependencies,” isn’t about total self-sufficiency but about cultivating trustworthy dependencies. The goal isn’t zero dependence, which is impossible, but discerning which relationships are resilient, personal, and aligned with your values versus those that are extractive or opaque.
6. Incentives Must Be Aligned with the Good: A core critique is that most digital services today—especially those driven by advertising—are fundamentally misaligned with human flourishing. They monetize attention and personal data, often steering users toward addiction or anxiety. Fixing this, Aaron suggests, isn’t about ...
