Reading List – 04/26/2026
This week’s reading list covers Tim Cook’s legacy at Apple, what actually matters when building AI agents for high-stakes financial services (hint: not the model), and Joanna Stern launching her own independent media company.

Tim Cook Personified Big Tech’s Maturity
Apple under Tim Cook went from disruptive innovator to $4 trillion operational machine. Jobs built new product categories. Cook optimized the machine that sold them: mastering supply chains, growing Services into a profit engine, and switching from risky live events to safe, pre-recorded ones.
His bet on China enabled Apple’s global scale. It’s also dependency which will be hard to break. His legacy is the story of big tech’s maturation. Not world-changing anymore. Just enormously profitable.

2. Lessons from Building AI Agents for Financial Services

Lessons from building AI agents for financial services – why sandboxes, domain skills, and data infrastructure matter more than models
Building AI agents for high-stakes financial services means treating the model as a commodity and betting everything on data quality and infrastructure. Context is the product: financial data has to be normalized into clean markdown and structured metadata before agents can reason accurately about companies, time periods, and numbers.
The edge isn’t in prompt engineering. It’s in the surrounding system: skill libraries that encode domain procedures like DCF (discounted cash flow) valuations, rigorous evaluations that catch financially meaningful errors, and data pipelines that no model upgrade can make irrelevant.

It’s Time. Meet My New Thing.
Joanna Stern left the Wall Street Journal to launch New Things, an independent newsletter and YouTube channel focused on consumer tech. The pitch: editorial freedom, direct ownership of her work, and coverage that centers on humans using the tech, not the tech itself.
All content is human-written, though her team does use AI tools to handle efficiency tasks. Her first video featuring Casey Neistat is fun and shows the personality she brings to her work.
