THE FAKE DOUBLE DIAMOND IS DEAD. THE REAL DOUBLE DIAMOND IS IMMORTAL

Summary from the TLDR Design newsletter

Synthetic users and AI-generated insights offer the false certainty of up-front discovery without its substance, and they never remove the need to iterate. Shipping everything and letting analytics decide fails too, because real experiments need a hypothesis, an end point, and cleanup of failed bets. The fake double diamond trades real divergence for synthetic urgency. Useful software needs problem definition and iteration in one shared system.
