This week: why a differentiated data model is the moat when AI makes code cheap, an Anthropic engineer’s guide to using AI more ambitiously, and Paul Krugman on France’s growing debt risk.
1. Your data model is your destiny

Matt Brown argues a startup’s core data model decides whether new features build a moat or just pile onto a feature list
Brown, a partner at Matrix, argues a startup’s data model, the core objects its product treats as central, shapes everything from the database to pricing and go-to-market. As AI commoditizes feature development, that choice matters more, because the workflows and habits customers build around it are hard to copy or switch away from.
Most companies shouldn’t innovate here, since customers already think in the incumbent’s model. But when AI makes features cheap and competition fierce, upstarts like Slack and Notion show that a data model built around customer workflows gives an edge incumbents can’t match.

2. How to be more ambitious: A tutorial for humans with models

Claude engineer Felix Rieseberg says AI users should aim higher in altitude, depth, and range
Rieseberg says model capabilities grow unevenly, so many people stop at simple tasks like polishing emails. He splits ambition into altitude, depth, and range:
- Altitude: aim at the outcome rather than the task
- Depth: work like a top professional with an outside judge
- Range: borrow perspectives from other fields
Altitude is the one I’ve tried recently, pushing the model up an abstraction layer. That can require a workflow change. The model needs access to the same things I do: the endpoints, databases, tickets, and knowledge systems I use. Since capabilities seem to shift every few weeks, it’s worth re-testing things that didn’t work before.

3. What’s the Matter With France?
Paul Krugman

Krugman says France’s frozen retirement reform and surging bond spreads risk a euro debt crisis
Financial markets are treating France as the sick man of Western economies, with bond yields and default insurance prices jumping more than elsewhere in Europe. The core problem is an unsustainable budget and a retirement reform frozen until after the 2027 election, with Marine Le Pen, who wants to restore a retirement age of 62, leading the polls.
Because France can’t print euros, a loss of confidence could spiral into a debt crisis the European Central Bank may not backstop. It’s a useful economic lens on the student protests, which follow cuts to education spending.
