Six months ago, I sat in a windowless room in Amsterdam while an engineer from a routing company I cannot name walked me through their new edge-rendering stack. The demo was flawless. Two-millisecond latency from a node in Frankfurt. The interface felt instant. And somewhere between the third and fourth slide, I realized I had stopped asking the uncomfortable questions.
The topology problem
Edge rendering solves for speed by distributing compute to the periphery of the network. But periphery always implies a center, and the center keeps logs. Every render pass generates metadata — timestamps, session fingerprints, the precise sequence of views that constitutes a user's attention. This is not surveillance by design. It is surveillance by default, a side effect of an architecture that treats state as something the server owns and the client borrows.
Every millisecond saved at the edge is paid for with a gram of opacity at the center.
