You type a question. A model answers one token at a time. Under that: TLS, gateways, prompt assembly, tokenization, transformer layers, KV cache, GPU kernels, batching, routing, streaming, and…
You click a button. A name appears. 200 milliseconds. Behind that click: DNS, TCP, TLS, HTTP, a load balancer, a connection pool, a database query, and every layer in reverse.
You flip a switch. Photons stream from a wire, cross the room, enter your eyes, and become seeing. Every step is the same force.
Your watch and your laptop both say 3:00 PM. They've never communicated. How?
