I've spent my career designing and building systems to help humans understand data and control computers. While I find this hard to swallow it's also hard to argue with. Tens of thousands of engineers and designers rebuilding slightly different drop-downs is an inefficient world that is unarguably coming to an end.

As so much of the first-line decision-making moves to LLMs there's definitely going to be opportunities for much richer and complex output from LLMs - how we can create terse and expressive visual summarisations/interfaces for where humans need to make decisions. But it's a much smaller world.

Where I suspect the wheels are going to come off for some though is that it's far, far easier to create a complex, difficult to understand UI than a simple one. And if simplicity and clarity are what enables effective LLM utilisation attempting to skip all that bothersome UX work will go poorly.
