In 2007, an unused key on the phone keypad became the internet's most powerful organizing tool. In this episode, we sit down with Chris Messina, the Carnegie Mellon University alumnus who invented the hashtag – now used more than three billion times a day – and famously gave it away for free. Messina shares the fascinating journey of the hashtag, from its roots in early "nerd centers&quot...

The smiley face in your last text, the Kevlar protecting first responders, and the Wi-Fi signal connecting us all—where did they actually come from? Welcome to Season 3 of Where What If Becomes What's Next , where we take you on a journey through 125 years of innovation at Carnegie Mellon University. To celebrate this milestone anniversary, we’re digging into the university archives to reveal...

What if machines could reason like humans? We're racing toward that reality. It's called artificial general intelligence. The question is, can we build it safely? In the second part of our conversation with Dr. Zico Kolter, head of Carnegie Mellon University's Machine Learning Department and OpenAI board member, where he chairs their Safety and Security Committee, we explore the critic...

What if AI is automating the one thing that's always made us human—Intelligence itself? And how do we ensure that it's developed safely? In this first of a two-part series, we speak with Dr. Zico Kolter, head of Carnegie Mellon University's Machine Learning Department and newly appointed OpenAI board member, where he chairs their Safety and Security Committee, to explore the critical c...

What if AI could help design gene therapies so precise they eliminate chronic pain while leaving other senses completely intact? And what if the secret to treating Parkinson's Disease lies hidden in the genome of a mouse? In this episode, we explore groundbreaking advances in genetic medicine with Andreas Pfenning, Associate Professor in Carnegie Mellon University's Computational Biology D...

What if AI could help emergency responders make split-second decisions that save lives during disasters? And what if that same technology could be used in healthcare to identify which patients desperately need care before it's too late? In this episode, we explore how artificial intelligence is revolutionizing emergency response and healthcare decision-making. Host Randy Scott interviews Aarti...

What if robots could pick apples without bruising them, detect diseases in tomatoes before farmers can see them, or even help prevent catastrophic wildfires? In this episode, host Randy Scott speaks with Professor George Kantor from Carnegie Mellon University's Robotics Institute. Professor Kantor’s two decades of pioneering work in agricultural robotics are shaping the future of food and sust...

Imagine a telescope so powerful it could give us a whole new picture of the cosmos and help answer some of the biggest questions about the universe–if we can handle the data. From a mountaintop in Chile, the Vera C. Rubin Observatory is revolutionizing astronomy. The Observatory began capturing images of the entire night sky in June 2025, launching the most ambitious astronomical survey in history...

The sound of someone chewing can be annoying. But what if only one specific person's chewing bothered you? And what if it went beyond annoyance to actual pain? In this the second of a two-part episode on the Science of Sound, host Randy Scott discusses with Professor Laurie Heller what happens when our brain's relationship with sound goes wrong. Heller is a professor of psychology at Carne...

We live in an increasingly noisy world. Our cities are louder than ever. Our devices can pump dangerous levels of sound directly into our ears. One in eight kids has permanent hearing damage.  And while we count calories and track our steps, most of us have no idea how much acoustic damage we're absorbing every day.  In Part 1 of a two-part episode, we explore the Science of Sound and its prof...

Happy Fourth of July from the Where What If Becomes What’s Next podcast team and Carnegie Mellon University.   As we celebrate independence and look towards the future, our host Randy Scott reflects on the spirit of innovation and forward-thinking embodied by Carnegie Mellon University.  For generations, CMU has been a place for questions, like:  What if we could teach computers to learn? What if...

What if instead of avoiding stress we actually leaned into it – and built resilience for next time? In this episode, we speak with Dr. David Creswell, a psychology and neuroscience professor at Carnegie Mellon University, about reframing our relationship with stress. Creswell argues that modern "comfort culture" contributes to rising stress levels because we avoid discomfort that actually builds r...
