Since no particular solutions were offered in the talk... HN: What are the best technologies for writing large JS apps? I have experience writing Closure (http://code.google.com/closure/ http://code.google.com/closure/) and its structure is pretty scalable, but it feels like so much effort to do simple things. Styling the widgets is a pain. Making a custom widget (extending goog.ui.Component) is surprisingly difficult to get right for even simple extensions. After all that, I still think it's probably better to develop in that over jQuery -- at least you end up with a straightforward, modular, testable structure at the end of the day. Is there something better? backbone?
