Technology arrives wearing the language of inevitability. Every system is still a collection of human decisions.
A useful technology does not merely make a task faster. It makes its assumptions visible. The interfaces we accept quietly decide whose time counts, whose knowledge is trusted and who is allowed to opt out.
The question behind the interface
A new service often arrives with a tidy diagram: one person, one problem, one direct path through it. Real life is less obedient. People share devices, translate instructions for neighbours and work around rules that were designed without them.
The useful design question is not simply whether a system is efficient. It is who can challenge its defaults, who can repair a mistake and who remains visible when the launch campaign is over.
