In the final episode of the Great AI Safety Debrief series with Dr. Petr Lebedev, we discuss job eradication, AI alignment and the rise in cases of AI deceiving humans. Petr unpacks ideas like AI scheming, situation awareness, parasitic relationships between humans and machines, and even the possibility of AI developing belief systems of its own. We end by zooming out to existential risk, Alan Turing's early warnings, and why aligning AI with human values may be one of the most difficult (and urgent) challenges humanity must face.

In part two, Dr. Petr Lebedev and I dive deeper into how modern AI systems are grown, not programmed, and the emergence of Shutdown Resistance. We explore AI performance in math and coding competitions, the rapid evolution of ChatGPT models, and why companies are already letting AI write the majority of their code. Petr explains how huge investments globally are pushing these systems forward faster than we can fully understand or control.

The final episode in this 3 part series drops next week!

Intelligence is emerging from sand and less than 1% of the population seems to care!

Physicist and science communicator Dr. Petr Lebedev joins the podcast following his SXSW talk to explore the rapid advancement of AI and how it's dramatically shifting the global status quo. From completing a PhD in physics and writing for Veritasium, to leading science communication at Palisade Research, Petr steps in to bring some clarity to the weird, wild, and worrying sides of AI.

Did you know that no one truly understands how large language models actually work? We go deep on misaligned systems, humanoid and dog robots, and why many experts believe AI could pose a serious global risk. Is AI our greatest tool? Or something we're slowly losing control of? This conversation is big, so we've split it into three parts. Part two drops next week.

A mysterious glow from the centre of the Milky Way has scientists intrigued. Astrophysicist Geraint Lewis explains how this gamma-ray excess, first detected in 2009, could be evidence of dark matter particles interacting deep in our galaxy. With dark matter believed to make up a vast, invisible halo that holds galaxies together, uncovering the source of this glow may bring us closer to understanding what the universe is really made of.

In this episode, I'm joined by Professor Clare Collins, Australian dietitian and Professor of Nutrition and Dietetics at the University of Newcastle. Clare is my go-to expert when it comes to all things nutrition, and today she's here to unpack the often confusing world of processed and ultra-processed foods.
We dive into what really separates the two, explore the role of additives, emulsifiers, and flavour enhancers, and discuss how some of these ingredients, designed to make foods more appealing, may be doing our health more harm than good. Plus, she shares practical, no-nonsense tips to help you make smarter choices next time you're wandering the grocery aisles.
