The Grand Challengers Podcast

We train AI systems to optimize for metrics — but what if the real alignment problem isn't in the machine? What if it starts with us?
Juan Pablo Carbajal is a physicist, interdisciplinary researcher, and educator at the Eastern Switzerland University of Applied Sciences (OST). Originally from Argentina, his career spans physics, robotics, biomechanics, agronomy, machine learning, and water research — driven not by any single discipline but by a deep need to understand the systems underlying everything he encounters.
In Episode 58 of The Grand Challengers Podcast, Juan Pablo joins host Peter Marcus Bach to reframe the AI alignment debate as fundamentally a human one. He argues that the same narrow, single-metric optimization we apply to AI — rewarding output over understanding — is already distorting science, education, and society. From the "publish or perish" crisis in academia to how we evaluate students with one-dimensional scores, the pattern is the same: pressure systems to hit a number, and unintended behaviours emerge.
The conversation traces Juan Pablo's journey from collecting tadpoles in an Argentine river (with a memorable food-chain disaster) to studying embodied AI at the University of Zurich's AI Lab under Rolf Pfeifer, where intelligence is inseparable from its physical body. Along the way, he shares lessons from plant biology — how nitrogen-fixing bacteria and their "cheater" free-riders coexist through tolerance rather than punishment — and explains why physics-informed AI may be the antidote to purely data-driven approaches that mistake local patterns for universal truths.
Topics include: the limits of data-driven machine learning, Gestalt psychology and machine vision, why the word "robot" means slave, complex systems and emergence, the role of culture as humanity's alignment mechanism, and why understanding history is our best defence against repeating its mistakes.

Every machine that lifts, digs, or hauls relies on hydraulics — a technology that hasn't changed in over 50 years. But what if you could replace that leaky, energy-wasting oil with a belt-and-pulley system that's three times faster, three times more efficient, and three times more durable, with zero emissions?
That's what Hiten Sonpal and his team at RISE Robotics are doing. In Episode 57, Hiten joins Peter Marcus Bach to explore his full robotics journey, from a childhood fascination with LEGO Technic in India to building bomb-disposal robots for Iraq and Afghanistan at iRobot, designing the Roomba lawnmower, and now leading RISE Robotics as CEO, where their patented Beltdraulic™ technology is disrupting the $600 billion hydraulics industry.
Hiten takes us inside the world of robotics: what counts as a robot, why humanoid robots are far from ready, and how AI is augmenting rather than replacing skilled workers. He explains why hydraulic systems waste 70% of their energy as heat, why electrifying heavy machinery has been prohibitively expensive, and how Beltdraulic solves both problems by replacing fluid with precision-engineered belts and sealed bearings.
The results speak for themselves. RISE's Guinness World Record-holding robotic arm lifts over 7,000 lbs fluid-free. Their military crane dropped from 1,800 lbs to 300. And their commercial liftgate saves delivery fleets $300–$1,200 per truck per day.
Hiten also shares the personal story of spending five years building a robot lawnmower at iRobot, only to have it cancelled by COVID, and how that adversity became the catalyst for his entrepreneurial career leading three companies as CEO.

Fred Jordan, scientist, entrepreneur and co-founder of AlpVision and FinalSpark in Vevey, Switzerland reveals the power of mathematics to us and how he thinks differently when it comes to computing. We dive deep into how he has combined industrial processing and digital watermarking to create anti-counterfeiting technology and uncover the mystery of "Organoid Intelligence", also known as biocomputing - using "the real thing" to compute. What was previously only written in science fiction novels (e.g., "wetware" from William Gibson's Neuromancer) is now becoming a reality! Tune into the longest episode on the podcast to date to hear about how Fred's love for science, technology and scifi has inspired him to make real disruptive change and how biocomputing could be the complement to our rapidly advancing semiconductor and AI industries.

Welcome to this Mini-Series on The Grand Challengers Podcast! The topic of generative artificial intelligence (AI) has been in all our minds over the past few years and is gaining even more momentum with rapid advancements in text, audio and video. Google's NotebookLM is a powerful research-support AI that can generate not only summaries of sources that we feed it, but also entire podcast episodes. This Mini-Series will explore the power of NotebookLM, our live reactions to its outputs... and a deep dive into some of the topics that we have covered on the show. We feature previous guests, who are here to join in on the fun!

Episode #10 is the final episode of this mini-series and we conclude by using the mini-series itself as the source for two other types of audio overviews that NotebookLM can generate: the Debate and Critical Discussion. Furthermore, I do this as a solo human, but converse with Martha and Stuart, the hosts of our deep dive discussions across the mini-series by using the "Interactive Mode". Will they be able to answer some challenging and existential questions and reflect upon the critique of their performance? Or will everything go awry? Find out in this spectacular finale and also learn about how you can get started with building AI literacy yourself.
