If an interface only works for someone who is fine, it wasn't designed for people. It was designed for an ideal user who doesn't exist.
An alert that stops you texting someone you shouldn't. A photo grid that hides but never erases. A playlist that knows which songs belong to which person. A dating app that reminds you something better is out there.
These aren't edge cases. They are the design brief for anyone who takes the full human seriously.
