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.

Big tech isn’t a buzzword anymore, it’s the scaffolding holding up the modern economy and, increasingly, modern politics. We sit down and map the real shape of power behind the Magnificent Seven: Apple, Microsoft, Amazon, Alphabet, Meta, NVIDIA and Tesla. We talk through what they do, why they dominate the S&P 500, and the part most people miss, where the revenue comes from versus where the profit actually lands. If you’ve ever wondered why Amazon can run on thin retail margins while AWS prints cash, or why Google Ads is still one of the greatest business models ever built, we make it plain.

From there, we zoom out to the global dependencies that make big tech feel both impressive and fragile. Taiwan’s TSMC sits underneath much of the semiconductor supply chain, and that reality turns “chips” into geopolitics. We also touch on non-US giants like ByteDance and Samsung, then bring it back to the West Coast to ask why Seattle and the Bay Area became such powerful innovation hubs in the first place, from universities and defence roots to talent density and network effects.

Then we get into the part everyone really wants: what it’s like inside these companies. We unpack Silicon Valley compensation and culture, including base salary, bonuses and RSUs, how vesting creates golden handcuffs, and why perks like free food and on-campus services can be both brilliant and slightly manipulative. We also talk about the uncomfortable employee vs contractor divide, and what performance cultures look like when KPIs and reviews are relentless.

Finally, we tackle the looming disruption: AI coding tools like Claude Code, vibe coding demos, and what happens when “writing code” stops being the main job. Are we heading towards fewer engineers, better engineers, or just a different definition of software engineering altogether?

We compare how we actually use ChatGPT (and Claude) every day and why most people treat LLMs more like a personal helper than a work automation tool. We dig into what happens to your data after you hit Enter, from memories and human review to cross-border storage and training settings.

We cover several topics:

• Our top real-world use cases for ChatGPT and why they are mostly non-work
• How ChatGPT memory works and what it can infer about you
• The "asking, doing, expressing" framework and why “expressing” feels new (it's not something you've ever done with Google)
• What the under-26s' usage stats suggest about adoption and behaviour
• Where your prompt data can be stored and why multiple jurisdictions can apply
• Why companies keep multiple copies of data and what that means for control
• How human-in-the-loop review works and how incredibly rare it is
• The ChatGPT “improve the model for everyone” toggle and what opting out changes
• Personality and tone settings in ChatGPT plus the risk of AI-fuelled echo chambers
