The main problem I think comes from the misconception that design = art. Because of that many artists making posters and print, are considered designers for lack of a better word.
It is assumed that if someone can draw using pen and paper, they can also draw using pixels (or vectors nowadays) but the distinction is not merely “lack of ux knowledge”.
I think it’s also about not being too “artsy” in the process.
Artwork can be a supplement to a design (like an illustration within an onboarding process) but the design itself has a purpose of delivering content.
So it can’t be front and center and definitely can’t be unpredictable and thought provoking (like art should).
The more logical way is for a UX designer to learn UI design, as the basic principles of “beautiful + functional + readable” are not that hard. Sadly that also doesn’t happen too often.
So we’re stuck with a couple unicorns (UX+UI) and:
- artists making completely unusable, chaotic UI’s (abstract paintings)
- ui artists making impossible to achieve dribbble apps (no data is ever that smooth on any graph, to give just one example) with little to no UX knowledge
There are more and more people trying to “learn” UI from the right (UX) perspective, so hopefully not all is lost.
But it’s good to push those people forward and encourage them, as we’ll all be using the interfaces they create.
