# Skills compound, prompts don't

> *"Skills compound over time — prompts don't… Prompts are becoming the basic four by four building block of Lego for the rest of the world. You still have to have the specialized Lego blocks to build the rest of the castle that you want to have."*

## Context

The Lego metaphor is the speaker's signature mental model: prompts = 4x4 baseplates, skills = specialized bricks. Anchors [[concept-skills-vs-prompts]] and [[claim-skills-compound]].

## Why It's Quotable

It reframes prompt engineering not as obsolete but as **necessary-yet-insufficient** infrastructure for agentic systems — and gives a vivid metaphor any practitioner can hold in their head.
