Shay Foulk: military, theology and the vibe coding death of ag apps

About this episode

Vance returns from a podcasting hiatus (prompted by his health scare) with Shay Foulk, a farm-consulting-business leader and National Guard veteran. The first half covers Shay's family business, Ag View Solutions, pivoting their decades-old "Profit Manager" tool into a free software product (Farm Profit Manager) using AI/vibe-coding — a strategic bet that giving away the tool for free will drive high-value consulting relationships instead. They dig into practical AI-development lessons (skill-based prompting vs. "black box" prompting, GitHub as a durable "skill library," mermaid graphs for debugging automations) with genuine technical depth. The conversation pivots into an extended, wide-ranging theology discussion: the Catholic-Protestant-Orthodox schisms, literalism vs. symbolism in biblical interpretation, the geographic/genetic theory that northern climates bred literalist religious cultures for survival reasons, the post-Charlie-Kirk-assassination religious resurgence, and the Vatican's explicit ban on AI-generated homilies. Vance shares a deeply personal account of his own faith journey — including a formative encounter with an elderly woman on a bus that sent him away from faith for over a decade before he returned to it as a parent. Shay discusses his recent appointment as a church elder and how his military deployment experience shapes his view of spiritual and civic duty. Closes with a Farm Profit Manager plug and the recurring IBC-course testimonial montage.

“I think many of our theological debates are actually geographic debates and they're actually genetic debates... the further north you go, the more your society has to be organized... the demand that you be a literalist came from generations of breeding.”

“Certainly the geographical outline there... [my family] ended up where we are today... we're so quick to forget the history of how we got to where we are 150 years ago.”

Key moments

• Vance's framing of returning to podcasting after a health scare, and his admiration for Shay after learning about Shay's military background at a January conference.
• Shay's account of the bold business decision to make Farm Profit Manager completely free, betting on consulting relationships over software revenue — reaching 1 million enrolled acres within 10 days of public launch.
• Detailed technical discussion of "vibe coding" best practices — building reusable "skills"/equations in AI tools (via GitHub) rather than one-off black-box prompts, illustrated with the "yelling at the AI" self-critique.
• Discussion of the AI-driven death of subscription "ag apps," with Vance's analogy of AI as a "magic carpet" that can replace $10K/month software stacks.
• Vance's observation about a surge in interest in Catholicism and church attendance, opening the extended theology discussion.
