You Can't Tune a Product — Show Notes You can tune a piano — the strings obey the wrench. You cannot tune a generative product, because its behavior is a trained prior, not a setting. This special edition tells the first-person story of the RCD pipeline itself: months of prompt detuning that failed to stop NotebookLM's "collision" dramaturgy, the forensic that proved it, and the pivot to verify-then-author — a Whisper-plus-LLM fidelity gate, then taking the pen entirely with verbatim two-host TTS. ...

The Bounds of the Cloned Voice In 2024, journalist Evan Ratliff cloned his own voice, wired it to a chatbot, and let it loose on the phone — and the thing that gave it away was a pause. This deep dive traces where that pause went. By 2026 the technical tells Ratliff relied on — latency, woodenness, the audible seams — have largely collapsed, which means the real boundary of the cloned voice has moved off the machine and onto us: our psychology, our laws, and the economics of who can afford to fake whom. The defense that still holds isn't a better detector. It's whether you and the person on the other end agreed on a code word in advance. ...

Two Modes, One Codebase: Durable vs. Disposable Code in the Age of Cheap Generation Durable and disposable code aren't two points on a quality scale — they're two different kinds of software with different cost models and different reasons to exist. AI codegen has collapsed the cost of the disposable kind and shifted the ratio between them, which makes the boundary between the two the real engineering skill: naming a piece's half-life up front, designing the seam so promotion or disposal is cheap, and refusing to let throwaway glue silently harden into a load-bearing production dependency. This deep dive starts from the four blog posts that framed the debate and checks them against the 2026 research, security data, and regulatory calendar. ...

Should You Be Nice to Claude? Three Spines, One Question, and the Answers That Don't Agree The viral question — does saying "please" and "thank you" to a language model matter? — looks like one question, but it's three. Efficiency, ethics, and tone-of-collaboration each answer it for different reasons, and once you separate them, the 2026 evidence stops contradicting itself. This deep dive walks the spines, finds where they diverge, and lands on what the evidence actually supports. ...

The Agent Stack Picks Its Three: MCP, A2A, AP2 — and What the Six-Protocol Era Still Doesn't Solve A special-edition deep dive on the six wire-format specifications competing to define the agent stack — Model Context Protocol, Agent-to-Agent, AG-UI, A2UI, Agent Payments Protocol, and x402. By mid-2026, three of them are pulling ahead as load-bearing infrastructure. The other three are smaller stories, and the most consequential parts of the picture are the gaps that none of the six, individually, solves. ...
