# Topic: Rethinking Architecture Through Residuality and AI

In short: Residuality Theory provides a way to dramatically improve your architecture - but it offers something else. It allows you to see architecture through completely new eyes, transforming your approach.

Agentic and harness engineering are an attempt to automate architecture. The failures and successes of these attempts will lead to new conversations about what architecture is. Residuality is well placed to answer these questions. And already we can see how some are using residuality to try and improve these efforts in books, talks, and academic articles.

If you’re an architect worried that GenAI is going to replace you, this talk should calm your nerves temporarily, until you realise how much work lies ahead of us!
