In this episode of Stewart Squared, host Stewart Alsop sits down with his father, Stewart Alsop II, for a wide-ranging conversation that moves from the technical to the historical to the financial. The two kick things off with Stewart's self-proclaimed evolution from "vibe coder" to "vibe engineer," as he tackles the tricky challenge of audio and visual sync in his own custom podcast recording software, positioning it as a direct competitor to platforms like Riverside.fm and Squadcast. From there, they get into a business breakdown of OpenAI and Anthropic, debating whether Claude's recent stumbles are a blip or a sign of deeper trouble, and what an IPO would actually mean for both companies as they look to compete with the big players. The conversation winds through a rich history of personal computing — from Mosaic and Netscape to PageMaker and the LaserWriter, desktop publishing, the browser wars, and how Windows 95 and the early internet reshaped everything — before landing on the turbulent state of the airline industry, the fallout from the Strait of Hormuz blockade, and what the collapse of Spirit Airlines says about fragile business models.

Key Insights

1. There is a meaningful distinction emerging between types of AI-assisted builders. Actual engineers use AI tools to boost productivity while still understanding code. Vibe coders use prompt engineering to build things without formal training. And then there are people who have no interest in building software at all because they simply do not need to.
2. Deterministic software is fundamentally different from probabilistic AI outputs. While the current hype around AI agents and markdown-based workflows is real, the underlying products are often insecure and unreliable. Building deterministic software first and layering in AI agents later is a more stable and trustworthy approach.
3. Desktop publishing in the mid-1980s was a landmark moment in personal computing. The combination of the Apple Macintosh, PageMaker, and the LaserWriter printer transferred control of page composition from professional compositors to individual editors and writers, democratizing the ability to produce print materials.
4. The browser wars of the 1990s, particularly Netscape running on Windows 95, marked the moment when the personal computer became meaningful to ordinary people. Before that, roughly a decade passed where developers and companies were still figuring out how operating systems, platforms, and application development were supposed to work together.
5. The MediaRecorder API is a significant but underappreciated limitation in modern browser development. Because Safari does not support it in the same standardized way as Chrome and Chromium-based browsers, many podcast and recording platforms are effectively locked to Chrome, creating an opening for alternative technical approaches.
6. Going public through an IPO gives companies like OpenAI and Anthropic access to capital at a scale that private fundraising cannot easily match. It also imposes mandatory quarterly financial disclosures, which means the public will finally be able to see actual revenue, spending, and growth figures rather than relying on perception and valuation claims.
7. Airlines represent one of the most operationally complex businesses in existence, involving gate leases, dynamic ticket pricing, fuel costs, crew logistics, and massive debt structures. The sudden spike in jet fuel prices following the US blockade of the Strait of Hormuz exposed airlines that had not hedged their fuel costs, contributing directly to Spirit Airlines going out of business.
