# Quoting Laurie Voss > Source: > Published: 2026-09-14 14:34:29+00:00 The cost of writing code collapsed, and the cost of reviewing, fixing and operating it is following, and I'm assuming it gets there. What's left of making software is finding out what people actually want, defining it precisely, and making it pleasant to use. That cost is per piece of software and doesn't transfer, so as the amount of software goes to infinity, which it will because there's no ceiling on demand, that cost becomes the whole job. — [Laurie Voss](https://seldo.com/posts/we-are-all-product-engineers-now/), We are all Product Engineers now Tags: [laurie-voss](https://simonwillison.net/tags/laurie-voss), [generative-ai](https://simonwillison.net/tags/generative-ai), [agentic-engineering](https://simonwillison.net/tags/agentic-engineering), [ai](https://simonwillison.net/tags/ai), [llms](https://simonwillison.net/tags/llms), [deep-blue](https://simonwillison.net/tags/deep-blue), [careers](https://simonwillison.net/tags/careers)
