I find this view fascinating. After decades of observing users getting lost by minor changes to UI or sometimes just different "paint" I am now to believe that we will all enjoy using completely custom UI customised not only to what I would want but what the app will think I need at particular moment and get on with it just fine.
I actually do think generating UI has some future, but I remain sceptical it can realistically go as far as promoters claim. It is especially bizarre to me when this is done by ostensibly UX people.
I am with you. For example - this post has a comparison of a recipe app from 5.6 and 6 for comparison. They look different. Now if every time I ask for a recipe, it decides to render a new UI because of either the model changing or the recipe goes from stove to oven or something, it’s going to become annoying very quickly. It just seems like he current generation of models have been tuned to create better UIs than previous one and people interested in the UI are getting hit with excitement.
Just depends where you think the limits of future AIs are.
Based on current capabilities, I'm skeptical as well. However, over time, I do think they will get better at understanding our intent. Also, I would be more forgiving of an app I vibe coded in this manner, that's only meant to be used by me. Of course that assumes appropriate security guardrails are in place.
