We mistook event handling for architecture

Events are essential inputs to modern front-end systems. But when we mistake reactions for architecture, complexity quietly multiplies. Over time, many front-end architectures have come to resemble chains of reactions rather than models of structure. The result is systems that are expressive, but increasingly difficult to reason about.

UI patterns for async workflows, background jobs, and data pipelines - LogRocket Blog

This same sense of uncertainty can be triggered in software products. Many digital experiences consist of background tasks, file imports, system updates, and other long-running processes that run quietly and invisibly, leaving users with no indications of progress or feedback. The user initiates an action, like a sync, a publish, or a bulk update, and is responsible for the outcome, while the system does all the work out of sight.
