Quadtree-based image compression formats and level-of-detail systems all work this way. Satellite imagery, terrain rendering, and geographic information systems use quadtree decomposition to serve data at varying resolutions: zoomed out, you see large coarse blocks; zoomed in, you see fine-grained tiles. The same principle extends to three dimensions (octrees) for volume rendering and 3D spatial indexing.

第三，是高竞争壁垒。在纯模型能力趋于同质化的当下，硬件构成了最直观的差异化壁垒。优秀的工业设计、紧密的软硬结合能力、独特的传感器阵列、乃至与时尚品牌的联名，这些要素共同构成了一个可被专利保护、难以被代码简单复制的物理实体。

The problem compounds because AI search is still in its explosive growth phase. Usage is doubling and tripling year over year as more people discover these tools and integrate them into their daily workflows. The traffic opportunity today is significant, but it's tiny compared to what it will become in the next few years as AI search becomes default behavior for entire demographics.
