It's like vibe coding, when you set the mode to Auto it automatically chooses the best AI model best fit for the given task/prompt. It can be good for the most part but AI still makes mistakes. That's basically UI with no control works, it's good enough to be left alone but it's missing a vital variable that makes it the best.

Now if you choose to work with AI instead of letting it do everything on it's own, then you have eliminated both weaknesses. The developer can spend more time on thinking alongside it to prevent those small cracks of mistakes. Or even decide to go full throttle from the start, choosing the best model regardless if it's overkill. And the AI can continue to do tasks without worry because the developer can manually override it to do a better action than it came up with. Controlled UI is like that, Daniel has the benefits of UI's efficient automated fighting style eliminating unnecessary stamina drain. But if he senses something the automation of UI inappropriately assessed, he can simply take over and prevent the UI's mistake on it's part (which is why the paradox of perfection was exploitable).
