Many of the things I do are considered a job of a “UI/UX” designer. But I haven’t ever called myself one.

That’s because the term “UI/UX” is badly designed: it’s tasteless and vague.

Tasteless

The abbreviations are used in science and tech, but when normal people talk, abbreviations are out of place. A good user interface is humane.

The way this abbreviation is constructed is wacky. First, it includes the word “user” twice. The good designer would not put a word twice where once would suffice. Second, it abbreviates “experience” with X instead of E. This comes from cheap marketing, where X used to sound “cool” and “trendy”. When a designer uses it, I feel like they disrespect the user and have shallow knowledge.

Vague

There’s a “/” in the middle, whose meaning is unclear. A slash usually implies an exclusive or. So does this mean “UI or UX, but not both”?

Good writers use conjunctions, not slashes. A slash is a way to slam two pieces together without thinking what sense the combination makes. This is not how you design a good user interface though.

The lack of taste and inability to communicate well are not the qualities of a good designer.
