Honestly, my hot take is that I don't think design itself has a visible skill layer; only the result of its application is visible. And even then, reverse-engineering the apple in order to get a sense of the tree that dropped it will never fully inform one of the architect's thesis.
I've been thinking a lot about visible vs invisible skill layers. i.e every craft has outer layers of skills that laypeople can recognise, and inner layers that you need expertise and experience to perceive at all. Could y'all think of examples of visible vs invisible skills in your own discipline?
