Signaling Theory is a roundtable with Rex Kirshner and a rotating group of builders who spend way too much time testing AI tools. They compare notes on what works for coding, how they manage context and workflows, what’s getting better fast, and what still breaks. Grounded takes, no evangelism.

    We Live in Science Fiction w/ Kenneth Eversole and Gerrit Hall

    Rex is joined by Gerrit Hall and Kenneth Eversole for a wide-ranging conversation on what AI is already changing, what people are still getting wrong, and where this all might lead next. They dig into enriched datasets, agent swarms, software deployment, the limits of today’s tools, the coming pressure on jobs, and why the AI boom may look less like a scam and more like an early, messy version of a very real future. It’s a grounded conversation about intelligence, infrastructure, human leverage, and what becomes possible when software starts to feel less like code and more like a medium.

    Build Once, Have Forever w/ Matt Silverman

    Rex sits down with Matt Silverman for a grounded conversation about what actually changes when AI agents become part of everyday work. They start with crypto’s uncertain role in an AI-first world, then get practical: voice-driven coding, parallel agents, custom internal tools, small personal apps, local models, and the idea that in a world where software gets rewritten constantly, the durable asset may be data, context, and trust—not the code itself.

    Live from ETH Denver w/ Gerrit Hall

    Rex sits down with Garrett in person in Denver for a wide-ranging conversation that starts at ETHDenver and ends at the future of AI agents as economic actors. They unpack the mood on the ground at a smaller, more subdued ETHDenver, debate whether Ethereum’s rollup-centric roadmap is being corrected or abandoned, and discuss why stablecoins may still be Ethereum’s clearest product-market fit. From there, the conversation pivots into AI: agentic coding, always-on tools like OpenClaw, what it means to build products for agents (not just with AI), and how financial rails may become essential infrastructure for machine users. Thoughtful, skeptical, and optimistic in equal measure.

  4. Sitting at a Slot Machine, a Claude Code story

    Sitting at a Slot Machine, a Claude Code story

    This week’s episode is a little different: instead of an interview, I’m reading an essay I wrote called “Sitting at a Slot Machine,” a candid story about falling headfirst into “vibe coding,” building an increasingly elaborate AI Context System, and realizing that unlimited execution can be just as dangerous as it is exhilarating. I unpack the dopamine loop of constant progress, the slow creep of complexity disguised as productivity, and the hard pivot back to simplicity... where the real craft becomes pruning, not piling on, and a few tight, well-chosen habits beat any sprawling framework.

    Shellmates: Tinder for Bots /w Dan Pollmann and Gerrit Hall

    Crypto’s melting down, so Rex sits down with Dan and Gerrit for AI Tools: Round Three—a conversation about what’s actually changing in day-to-day work when models ship, agents run in parallel, and “sessions” start to feel like a lifestyle.  They react to a big model-release day (Opus 4.6 + ChatGPT 5.3), compare Claude Code vs Codex for real coding work, and unpack why Claude feels so sticky: better UX, more glazing, and a dopamine-loop quality that’s hard to ignore once you notice it.  From there it gets practical: managing context windows with dashboards and handoff files, building bespoke internal tools (like Rex’s “notification hub”), and watching weird new ecosystems form — Moltbook-style bot social networks, and even “Tinder for bots.”

  6. Building with Agents Part 2 w/ Gerrit Hall & Dan Pollmann

    Building with Agents Part 2 w/ Gerrit Hall & Dan Pollmann

    Are we building useful developer tools—or just feeding an addiction? In the second episode of our AI tools series, Rex, Dan, and Garrett dig into the internal systems they've built around Claude Code: markdown session logs, pre-commit hooks, context management strategies, and notification hubs. Dan shares war stories from running AI on helicopters inspecting power lines (including the time an agent changed his root password without asking). Garrett walks through his approach to scaling ten concurrent projects. And Rex asks the uncomfortable question: is all this meta-tooling actually helping, or are we just tinkering because it feels productive? The conversation moves to local LLMs—Qwen, DeepSeek, Mistral—and whether a $15-20k home lab makes sense when Claude iterates faster than anyone can keep up. The hosts wrestle with context window limits, the ROI of refactoring, and what it means that these tools are specifically designed to make you feel like you're accomplishing more than you are.

    Building with Agents w/ Gerrit Hall & Taylor Savage

    Rex digs into how AI coding agents are changing the way real teams build software. Taylor Savage and Gerrit Hall share the workflows, tools, and guardrails that actually work: from custom IDEs and inbox-driven agents to multi-pass code reviews, collaboration at “agent speed,” testing that matters, and keeping data safe. A grounded look at what to automate, what to supervise, and how to ship faster without losing the plot.

  8. A Conversation with a Crypto-Skeptic w/ Taylor Savage

    JAN 22

    A Conversation with a Crypto-Skeptic w/ Taylor Savage

    Rex brings on his longtime friend Taylor Savage — a lifelong “techie” turned software engineer and product manager — for a candid, outside-the-crypto-bubble conversation about what crypto actually looks like from the broader tech world. From an early Bitcoin birthday gift (and an early sale…) to the last decade of fraud “speed-runs,” they debate irreversibility, regulation, institutional adoption, and whether crypto’s real promise is narrow-but-real or mostly drowned out by hype and extraction.
