AI lets designers build wild ideas, but knowing the low-level stack matters more than ever

Tyler Angert argues that while AI models let designers implement their wildest ideas, this makes understanding the lowest levels of the stack even more important. He demos three features for Angles (instant app launch, an infinitely zoomable photo grid grouped by day/month/year, and a seamless 2D map-to-3D globe with zero lag) and shows they all hinge on one component: a really fast image thumbnail cache and its management. Data retrieval speed is the shared performance bottleneck across all three. Owning the entire rendering pipeline, he notes, makes anything possible on a GPU. Angles 1.0 is coming soon.
