AI is certainly adding new layers of innovation to the interface but I don't think it will ever replace it. It does feel like we're entering a new era of simplifying all the "bloat" as referred in this article. I think the future of things to come will be starting to make sense of all the bloat in more innovative ways as more more apps just get added everyday while the main interface (phone, tablet, monitor) doesn't innovate or establish a better interface based on first principles.
