I don't see jQuery going anywhere any time soon. On the other hand, I don't hold out much hope for jQuery UI. The majority of the development effort appears to be going the way of jQuery Mobile these days. They're establishing useful conventions that are expected to eventually filter back into UI, but there have been other jQuery UI components under development for years now. Twitter Bootstrap appears to have most of the web momentum, and I think it will take a concentrated effort for jQuery UI to compete - even if they're providing slightly different functionality.
