Universality is not designed in. It is selected by surviving constraints, and the constraint is usually a person.
This UX Collective piece argues that the weakest channel in any system determines what gets through, and that weakness is almost always human. The argument reframes accessibility and inclusive design not as ethical add-ons but as structural inevitabilities: systems that ignore their lowest-bandwidth users do not become universal, they become brittle.
The full piece is worth reading for how it traces that logic through real design decisions, not just principles. If you build systems that assume ideal users, read it before your next sprint.
