Coffee
Coffee's reliability presents notable variability across multiple dimensions. Brewing outcomes depend upon water temperature, grind consistency, extraction time, and bean freshness—variables that can transform a potential masterpiece into an undrinkable catastrophe. Even professional establishments experience inconsistency, with consumer complaints citing flavour variation as a primary concern.
Supply chain reliability has proven equally precarious. Climate change threatens 50 percent of suitable growing regions by 2050, whilst coffee rust disease (Hemileia vastatrix) periodically devastates plantations. The morning coffee ritual, so central to millions of daily routines, remains contingent upon a complex global infrastructure vulnerable to disruption at numerous points.
Death
Death demonstrates absolute reliability unmatched by any other phenomenon in human experience. It has never failed to arrive, has never been successfully postponed indefinitely, and requires no infrastructure, maintenance, or quality control protocols. Whether in the most advanced medical facility or the most remote wilderness, death performs its function with unwavering consistency.
The timing, whilst variable, is guaranteed. No warranty could match death's 100 percent fulfilment rate. This reliability has persisted across all of history, affecting every organism from the simplest bacteria to the most complex mammals. When measured against coffee's temperamental brewing requirements and supply chain vulnerabilities, death's dependability is simply beyond comparison.
