The author details how LLMs' non-deterministic outputs, variable latency, and context-window constraints force architects to rethink patterns that have been reliable for two decades. The 26-comment HN discussion surfaced practitioner examples of teams struggling to apply traditional distributed systems thinking to LLM-backed services.
