We answer listener questions and Hugh fails to answer Hannah’s trivia questions (in a throwback to Episode 1).

We start with reflections on learnin...

A taxi pulls up with no one in the front seat. Would you get in? We invited Waymo director Nick Pelly to take us from that first uncanny moment to the engineering that makes a driverless ride feel calm, confident and, by the data, far safer than most humans behind the wheel.

Ever joined a “Guest Wi‑Fi” that looked legit, rushed through an email on the way to the airport, or reused a password because it was easier? Those small shortcuts are exactly where hacks begin. We open the curtain on how attacks actually work and, more importantly, the simple habits that stop them.

We break down malware in clear terms: old‑school viruses that ride dodgy attachments, worms that replicate on t...

A fake contractor calls the help desk, a password gets reset, and suddenly a national retailer has hackers inside. We open the door on the human side of hacking—how believable stories and helpful habits become the first domino—then trace the technical steps that turn a small foothold into a system‑wide crisis.

We walk through the anatomy of the Marks & Spencer breach: social engineering as the entry point...

You get a Jaguar car ranking first for an iPod query on eBay, and you get the perfect setup for a practical tour of how AI actually creates value. We unpack the journey from brittle if-then logic to machine learning that learns relevance from real outcomes.

In this episode, we break down AI, machine learning, and large language ...

Catastrophic software failures can seem like acts of chaos, but behind every major tech outage lies a story of human decisions, technical constraints, and cascading consequences. The July 2024 CrowdStrike incident—which Hannah describes as "the single biggest outage in the history of computing"—offers a perfect case study into what happens when critical systems fail.

Hannah and Hugh dive deep into h...
