Where the term shows up In this channel's material, the design diamond names the shape of design work that Figma's Matt Colyer describes when explaining how AI changes product development: a period of broad exploration followed by a period of convergence on a decision. The useful twist in the discussion is that AI compresses the generating side of the diamond, which shifts the real work — and the real bottleneck — to the other side: review and judgment[^9accf9e7]. Why it matters here The conversation around the design diamond is used to argue that the SaaS apocalypse narrative gets things backwards. If machines can produce many candidate designs cheaply, the scarce human contribution is not output but the ability to explore, evaluate, and converge on what is actually right — which is why the episode lands on how careers and design workflows are rebuilt around agents and MCP. - The design diamond is the diverge-then-converge shape of design work: explore widely, then narrow to a decision.- In this material, AI makes generation cheap, so review becomes the bottleneck of AI-assisted product work.- The diamond frames the episode's bigger argument that the SaaS apocalypse story gets things backwards.
