About Podcast

Matt Hempel opens Graybeard Radio by naming its audience and aim: men 50+ who care about health, relevance, and connection—and who want to use technology without losing their humanity. He welcomes guest Luke Thomas, lead pastor of Legacy Church in Knoxville and a veteran of 20+ years planting churches and campus ministries across Texas, Florida, and Tennessee. Luke’s formal training spans biology, chemistry, and human physiology, which later collided with the reality of ministry demands. In 2011, he hit a wall—too sick to lead—triggering a turning point that reshaped everything.

Luke recounts being accepted to medical school, becoming a Christian around that same time, and ultimately stepping away from medicine to plant and pastor. The early wins and hard misses taught him that calling without capacity is a trap. His recovery from burnout led him to research stress science across disciplines, self-experiment through training and recovery, and build a coaching and speaking practice centered on leadership self-care. He brings a grounded lens—equal parts science and pastoral wisdom—anchored by endurance racing: ultramarathons, Ironman triathlon, and a commitment to unglamorous rest (including hammock time).

Together, Matt and Luke preview Luke’s book on burnout in leadership, especially among pastors. They explore why high empathy and high responsibility often mask creeping overload, how to recognize red flags earlier, and how to rebuild patterns that sustain decades of meaningful work. Expect practical takeaways: physiological basics for energy, boundary-setting that respects relationships, and playbooks for teams to normalize recovery. The heart of the conversation is hope: longevity is possible when leaders align purpose, practices, and pace.

The Canary in the Coal Mine: Software, Young Men, and an AI Transition

On this episode of Greybeard Radio, host Matt Hempel sits down with Erik Newby, Director of Global Software Engineering at Red Hat, to unpack how AI agents are reshaping the software development lifecycle across a 600-person organization. Eric traces his arts-meets-tech path from design studios to leading global engineering teams, then explains the recent inflection point in frontier models and tooling that pushed AI beyond chatbots into real orchestration. He urges developers to move “up the stack” into systems thinking, decomposition, judgment, and communication—because isolated code typing is quickly becoming automated. The conversation zooms out to the deeper human story: young men wrestling with isolation, meaning, and mental health in the age of social media. Citing Jonathan Haidt’s work, Eric warns that AI may intensify addictive engagement and that mentorship and genuine relationships are the antidote. He shares how Red Hat supports people holistically and describes the leader’s job now: articulate a hopeful vision through the transition—an Industrial Revolution 2.0 that ultimately expands opportunity. A standout moment: Eric remotely prompted an AI agent to ship app features in minutes—from a beach—showing how barriers to building are collapsing. His counsel to youth is simple and timeless: cultivate human skills, find mentors, ask for help, and dream big. Eric grounds his optimism in faith, history’s rhymes, and community. He also plugs his AI-powered reading app, Shelf Checkout (shelf-checkout.com), and his handle @RaleighAwesome.

Stepping into the Breach (Why This Is Our Time)

Stepping into the Breach (Why This Is Our Time)

In this galvanizing episode of Graybeard Radio, host Matt Hempel examines why so many young men feel unmoored—and what older men can concretely do about it. Matt traces a cultural shift over the last 30–40 years: society moved from rightly correcting harmful behaviors to subtly dismissing men’s constructive strengths. In parallel, younger men are navigating real headwinds—AI-driven job disruption, a brutal housing market, and a confusing relationship landscape. The result: anxiety about purpose and place. Matt argues that men in their 50s, 60s, and 70s—those who’ve built careers and families and weathered economic cycles—carry a unique responsibility and opportunity. He calls this “crystallized intelligence”: hard-won judgment, pattern recognition, and context that AI can’t replicate. He reveals what younger men truly need: validation of their instinct to build, provide, and protect; a pragmatic map for careers and relationships; hope grounded in lived experience; and leadership modeled by purposeful lives in action. The episode is rich with stories. Matt recounts a conversation with a late-20s professional who felt shamed for wanting to provide for a future family. Matt’s response—“You’re not a caveman; you’re a man”—offered permission and relief. He also describes a dinner with younger professionals who weren’t seeking a perfect guru, just honest lessons about what worked, what failed, and what he’d do differently. Matt’s action plan is practical: speak up when narratives dismiss men’s contributions, mentor at least one young man, document and share your wisdom (see greybeardassessment.com), and model purpose by continuing to build and contribute. He frames this as cultural triage: a society of purposeless men is unstable. He ends with a one-action challenge—do one tangible thing this week—and teases an upcoming AI expert to discuss work and economic impacts.
