I totally agree that most people underestimate the complexity of building a successful UX. I think the impact to the UI/UX was mainly in Vibe Coding, they can build a similar thing just by upload a picture, that save lots of time on me to tune the css! Although we cannot rely on it as it really a nightmare on building a maintainable code base product, but it do show me the PoC on how. Time is money, so the AI Era did help me a lot, cheers~
