No they won't. They're actually a pretty terrible user interface from a design perspective.
Primarily because they provide zero affordances, but also because of speed.
UX is about providing an intuitive understanding of available capabilities at a glance, and allowing you to do things with a single tap that then reflect the new state back to you (confirming the option was selected, confirming the process is now starting).
Where AI is absolutely going to shine is as a helpful assistant in learning/using those interfaces, much as people currently go to Google to ask, "how do I do a hanging indent in Microsoft Word for my Works Cited page"? For one-off things you do infrequently, that's a godsend, don't get me wrong. But it's not going to replace UI, it's going to assist.
And the 99% of your tasks that are repetitive habit will continue to be through traditional UI, because it's so much more efficient. (Not to mention that a lot of the time most people are not in an environment where it's polite or possible to be using a voice interface at all.)
