About this video

​ ​ As the head of design at Cursor, Ryo is at the cutting edge of designers who ship code instead of mocks.

He showed me how he built a retro OS with AI and did a live demo of adding a new feature using Cursor’s new agent mode.

We also covered how to avoid AI design slop and how the Cursor team reached $29B valuation without full-time PMs.

Ryo and I talked about:

(00:00) Why designers should go directly to code (02:06) Building a retro calculator app in one shot with plan mode (08:04) How Ryo manages multiple AI agents at once in Cursor (15:18) How Cursor builds without PMs and who does the PM work instead (16:43) How to avoid creating purple AI design slop (it’s not prompting) (20:01) Inside RyOS: A beautiful retro operating system built with AI (27:13) How the Cursor team builds new features (30:22) How to turn vague ideas into detailed specs with Cursor (37:47) The fastest way for PMs and designers to learn Cursor
