TL;DR. LLM chat is eating the interface moat — vertical software's premium pricing dies when API-vs-API replaces workflow lock-in.

Takeaways

• Aggregation Theory's missing chapter: Web 2.0 commoditized discovery but left suppliers their interface and data. LLMs absorb the interface layer, leaving only the API.
• The real moat in vertical SaaS (Bloomberg, legal, medical, recruiting) was never the data — it was a decade of muscle memory and hardcoded workflows. LLMs erase both.
• "I haven't used Google in a year. An LLM chat is my browser." When the chat IS the interface to everything, conversion funnels, paywalls, and brand persistence collapse.

TL;DR. The dream job is one where being fully yourself is the work — solving problems you're compelled by and cutting anything that doesn't stretch you creatively.

Takeaways

• "Getting paid to be yourself" reframes career success as alignment, not achievement.
• Filter test: if the work doesn't challenge you creatively, eliminate it.

TL;DR. Resumable streaming is mostly solved by Vercel's package—the remaining glue is ~40 lines you can drop into send/resume endpoints.

Takeaways

• Vercel ships a package that handles the hard parts of resumable streaming.
• The author wrote ~40 lines as a reusable function to call from send and resume endpoints.
