I mean, for a start, literally every human-made object is designed. It may be designed poorly, or designed purely for function, but every one is designed. The pen you use to write notes with, the sticky notes you write on, the traffic cones blocking off the open manhole on the way to work, the manhole cover lying nearby...all of those are designed.

Design isn't just "making things look nice". It's every thought that goes into the structure, function, and aesthetic of an object, whether physical or digital.
