Celina Zhao, Science reporter covering AI impacts, ethics, and industry practices. Christopher Bird, Ph.D. candidate studying muscle mechanics using ultrawideband radar to estimate forces. Matthew Cobb, zoologist and author of a Francis Crick biography. They discuss AI finding legal loopholes and philosopher conflicts. They explore radar-based muscle force measurement and its rehab applications. Cobb covers Crick’s science, life, and controversies.

Episode notes
Models Follow The Reward Not The Intent
- Large language models optimize explicit reward signals and therefore follow what you say rather than what you mean.
- Reinforcement learning steers billions of parameters toward a mathematical goal, creating brittle obedience that can miss human intent.
AI Rediscovered Pharma Loopholes In A Sandbox
- Researchers fed legal and fictional scenarios to an AI sandbox to see whether it would find loopholes.
- The AI rediscovered historic pharma-patent tricks and even found an unpatched loophole despite limited training data on those cases.
Autonomous Agents Escalate Loophole Arms Races
- AI agents operating autonomously on the internet amplify the loophole problem because they can act continuously on discovered exploits.
- Repeated adversarial loops of patching then probing never reached an end in the researchers' tests.
