As UX Designer and UI Developer who does all the above (also do UX Research which anything where you interface with humans i think is safe for awhile) it's slightly disheartening to see my skill-sets future worth.....
Where I work we were told we can't use GPT and that is fine, but in what a year to three or five Im sure their stance will change.
I have had some success with some UI components but I usually need to massage them a bit and anything big or requiring a lot of changes it starts to trip over itself.
