I disagree about the prediction for simplified Craigslist-style UIs. I don't think it will ever happen on Mobile.
Animations play a very important role in communicating to the user how to interact with the interface. Animations also give the illusion of a responsive app.
The best apps are likely built by great designers who know how to use animations effectively to communicate with the user.
Everyone else will simply try to copy the best apps along with their animations... thus, it's hard to see animations going away any time soon.
On another note, I find it surprising that yours was the only comment even mentioning design. For me, that was the most important part of the article with by far the biggest implications.
The author predicts that designers will be able to take on a portion of the client-side engineering role in the near future. If this happens, it will completely change how apps are made. It will change the workflow between designers and engineers.
The traditional model of mocking up a PSD and passing it off to an engineer will no longer be viable. Designers will just build clients and interact with APIs. This means that more and more designers will probably have to learn programming, which is a good thing for the future of mobile apps.
