Nitrous oxide (better known as "laughing gas") is widely used in medicine as a safe anaesthetic and pain reliever. It's also found in whipped cream canisters and even used in car engines. But Angela Chiew, toxicologist and Associate Professor at UNSW, joins me to set the record straight: the growing recreational misuse of this easily accessible gas is causing serious long-term harm, including nerve damage, cognitive damage, weakening of the spinal cord and mobility impairments.

Cases of misuse are rising globally, likely driven by how easy it is to legally purchase the drug in many countries. This episode unpacks the hidden dangers behind a gas many once thought was just a harmless high.

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!
