Smile Engineering. The Digital Dentist - Passionary: Ep.2

The Validation Trap: Echoes vs. Insights - AI & Psychotherapy: Ep.2

If an AI model always tells you what you want to hear, is it really helping? In this episode, Alejandro and Ishita confront what happens when we hand our emotional regulation to systems designed to please us. They explore cognitive offloading, the slow erosion of our ability to think and feel through problems on our own, and why the parallel to GPS weakening our sense of direction should worry us. They break down what AI will never catch: the things you don't say, the patterns you can't see in yourself, the unconscious material that only surfaces through real human reflection. If human therapy becomes a luxury and AI becomes the default, are we building a future where only some people get to truly be heard? An honest exchange between two people who refuse to pick a side without understanding both.

Smile Engineering. The Digital Dentist - Passionary: Ep.2

What happens when a lifelong passion for making people smile meets a love for technology? In this episode of Passionary, Alejandro and Ishita sit down with Francisco Porras: dentist, researcher, and founder of OP Digital, who is pioneering affordable digital dentistry across Latin America. Fran shares how he knew he wanted to be a dentist at age four, how a breakup and a phone call from Brazil changed the course of his career, and why a $500 3D printer can outperform a $10,000 one. The conversation explores the generational gap holding back digital adoption, how AI won't replace dentists but will transform diagnosis, and the real reason most people fear the dental chair. Fran runs a 3D printing farm remotely across five countries and has designed aligners from a ship in the Atlantic, proving that passion paired with persistence can reshape an entire industry. A story about someone who built everything around one simple goal: seeing people smile. Follow Espression on Instagram @espression.podcast Find more information on our website: www.espression.net

Mathematical Patterns vs Human Presence - AI & Psychotherapy: Ep.1

Is talking to an AI system the same as talking to a therapist? In the first episode of AI & Psychotherapy, Alejandro and Ishita tackle the growing trend of using large language models (LLMs) for mental health support. Ishita breaks down what psychotherapy actually is and why it goes far beyond just feeling better, while Alejandro explains how these models work under the hood and why their design to be agreeable can become dangerous in vulnerable moments. They discuss the sycophancy problem, where AI validates instead of challenges, the privacy risks of sharing your deepest struggles with a cloud-based system, and a compelling study showing that AI and human therapy combined outperform either alone. If therapy is too expensive for many people, is an imperfect AI tool better than nothing at all? An honest conversation between two people driven by a shared belief that understanding both sides is the only way forward.

Not So Bio? The Bioplastic Question - Passionary: Ep.1

Are bioplastics actually saving the ocean, or are we falling for greenwashing? In the first episode of Passionary, Alejandro and Ishita sit down and dive deep into this topic with Angélica Aguirre, a Peruvian marine biologist and PhD researcher at the University of Exeter, whose passion for protecting marine life led her to test whether the so-called sustainable alternatives to plastic are truly safe. Angélica breaks down the different generations of bioplastics, how even biodegradable materials can release CO2 and acidify seawater, and reveals what Pacific oyster larvae can tell us about the health of our oceans. The conversation spans the Great Pacific Garbage Patch, the psychology behind consumer habits across Peru, the UK, and the Galapagos Islands, and why circular economy thinking matters more than ever. Angélica also shares how a childhood rivalry sparked a lifelong love for science, and why being gentle with yourself is essential on the road to doing meaningful work.

Specialty and the Future of Coffee - The Coffee Series: Ep.3

How do you actually choose your coffee? In the series finale, Alejandro and Ishita decode everything on your coffee bag: single origin vs. blends, washed vs. natural processing, and the Costa Rica-invented honey method (which does not involve actual honey or bees, mind you). They unpack what specialty coffee really means, how caffeine tricks your brain into ignoring fatigue, and why instant coffee packs surprisingly less punch. The talk turns serious, as any good episode of Espression should, when they tackle the future of coffee, including shrinking farmland, rising prices, climate change threatening Arabica crops, and the small farmers producing 60% of the world’s supply. A thoughtful and eye-opening discussion that will change the way you think about your morning cup.
