This week Hannah is joined by guest host Derrick Connell to discuss how Microsoft's Tay went wrong, how Satya Nadella reacted in the moment, and what Derrick learned about innovation. Derrick also shares stories from shifts in technology and discusses his new book Twenty One Summers.

Derrick shipped a chatbot that survived for 18 hours as it went horribly wrong. It sounds like a punchline until you realise it helped rewrite how the industry thinks about AI safety. Hannah sits down with Derrick, a former Corporate Vice President who spent nearly three decades at Microsoft and led teams across Search and AI, to unpack what innovation looks like when you are shipping into the real world and the real world fights back.

We talk through the massive platform shifts Derrick lived through, from Windows and Office shipped on discs to cloud services that ship daily, plus what it took to build Bing while Google held the vast majority of the search market. Along the way we get practical about product development methods, why agile experimentation changed the pace of software, and how “scrappy” teams innovate when they are not expected to win.

Then we go deep on conversational AI. Derrick explains why China’s WeChat environment made early chatbots thrive, how training data and user behaviour shaped outcomes, and why the US launch of Tay on Twitter was vulnerable to bot attacks and manipulation. We also get into the leadership playbook after a public failure, the importance of asking “What did we learn?”, and how that moment pushed Microsoft to publish early AI ethics guidelines that influenced responsible AI practices across the industry.

If you care about AI product management, innovation leadership, chatbot design, LLM guardrails, and what it takes to build safer AI systems, this conversation will give you both a story and a framework.

Google Search feels like magic because it is solving an impossible problem on your behalf: you show up with a complex information need, type a couple of words, and expect a great answer almost instantly. We unpack what’s really happening in that split second, from the early days of cluttered 90s search engines to why Google’s clean interface, speed, and relevance changed everything.

We walk through the core machinery that makes web search work: crawling (and why it has to be “polite” to websites), building and refreshing a copy of the web, and using an inverted index so results can appear in around 200 milliseconds. From there we get into ranking, including PageRank and why links became a proxy for credibility, plus the constant battle against spam and how SEO sits in a tricky grey zone between good practice and gaming the system.

Then we zoom out to what’s changing now. Human judges still evaluate search results at industrial scale to improve quality and train machine learning systems, while query understanding rewrites and repairs your input so the ranker has a fighting chance. Finally, we tackle the shift away from the ten blue links era as AI summaries and LLMs like ChatGPT reduce clicks, introduce new trust issues, and force new monetisation choices that could reshape search again.

AI did not creep in quietly, it arrived like a tidal wave. We talk with Ramez Naam, computer scientist, science fiction author, futurist, and climate tech investor, to pin down what today’s large language models really are, why they’re the fastest adopted general technology in history, and why “impressive” is not the same thing as artificial general intelligence. Along the way, we challenge the idea that AGI is right around the corner, even as these tools already outperform any single human on breadth of knowledge and rapid synthesis.

We get practical about capability and risk: where ChatGPT, Claude, and Gemini shine, where they still fail, and why supervision and verification are the new baseline skill for knowledge workers. We also unpack why the AI model race keeps flipping leaders, why user data may not create the kind of network effects people assume, and what recursive self-improvement would need to be real rather than wishful thinking.

Then we go straight to the biggest near-term shock: coding with AI. Vibe coding and modern developer tools are collapsing the distance between an idea and a working app, which raises hard questions about software engineering careers, junior hiring, and what “good” looks like when you are managing an army of bots. Finally, we zoom out to the energy and infrastructure behind AI, from data centres and grid bottlenecks to the case for solar-and-battery powered compute, including why Australia could be well placed.

If you’re curious about the future of AI, AI jobs, AI reliability, data centres, and what the next ten years might realistically hold, this conversation will give you a grounded framework.
