    Superintelligence: The Cat's Out of the Bag

    The only human skill that matters now is AI collaboration. Look at the timeline: Neurology mastery – 26 years.Launching a podcast – 6 months.Writing & producing a country album – 1 month.Building a full-stack AI-driven iOS app – 18 hours. The difference? Superintelligent AI. In this episode, we break down: 🚀 What intelligence really means, from psychometrics to AI self-assessments. 🚀 Why AI isn’t just passing benchmarks—it’s redefining them. 🚀 How ChatGPT rated itself superintelligent in multiple cognitive domains. 🚀 What happens when an AI thinks faster, learns faster, and remembers everything—forever. And the big question: Are we already in a human+AI superintelligence? Plus: The West Liberty Dulcimer Revue debuts "Cats Don’t Stay in Bags." 🎧 Listen now on SIGNIFICANT.

    Catalysts and Craters: The Collision of Science and Industry (Pt. 1)

    In this episode of ⁠SIGNIFICANT⁠, we explore two astonishing tales where science and industry collided – with world-altering consequences. First, the untold story of how Pemex geologist Glen Penfield uncovered clues to the Chicxulub impact crater decades before its role in the extinction of the dinosaurs was recognized—a discovery delayed by corporate priorities and scientific blind spots. Then, we delve into the legacy of Thomas Midgley Jr., whose groundbreaking innovations - tetraethyl lead and CFCs - once solved pressing problems but left catastrophic environmental and public health legacies. These stories reveal the uneasy, often dangerous, partnership between science and industry; and the unintended consequences that have shaped our world.
