I’m Geoff, and I’m going to be building 42 AI prototypes in public over 2026 - 42-26. Each prototype will attempt to tackle a “hairy problem” - something that doesn’t have a solution just yet, and may benefit from the fresh models and approaches coming through the AI boom. This blog will be capturing what worked and what didn’t. It will also have shipped, accessible demo’s available for anybody to poke at.
