The expert-beginner trap in framework-dependent careers

Being fast in React (or Angular, Spring Boot, etc.) isn't the problem
- the problem is when the framework becomes the only place you can
think, so that when the stack changes or a question falls outside your favorite abstraction, the thing you were hired to be great at is the only thing you can explain. That's a career dependency, not specialization: the "expert beginner trap" of solving hard work through one abstraction without understanding the principles it hides. It looks like competence on the happy path and gets exposed on the first ugly cross-system change.
Illustration: a checkout screen where a discount decision is duplicated across the React component, the API handler, and a convenience service reaching straight into the database. It ships fine - until one business rule change (stacking a contract discount with a promotion) requires the UI, API, query, tests, and a deploy flag to all move together, because the framework became "the filing cabinet for the company's decisions" instead of an implementation detail of a business rule that should live in one place (e.g. a checkout-policy module that answers "can this customer combine these discounts?" once, with everything else calling into it as an adapter). Framework-first speed is fine for an MVP as long as you know it's a shortcut and don't let the business rule stay buried in it forever.
AI raises the stakes here: it can write the familiar component, handler, and query fast, but if it's doing the thinking you were supposed to do, you ship "a tidy lie" that works only until the question changes - tracing state, policy, data, dependencies, and failure modes afterward is still engineering judgment, and AI doesn't do that part. Proposed self-check, the "Monday test": pick one request that matters, trace it from screen to business rule to data to deployment/monitoring, and before asking AI for a fix write a hypothesis - what decision is this request making, where does that rule live, what breaks if the UI/data model/framework changes? If you can answer that, the framework is a tool; if you can't, "you're not owning the code, you're renting it."
