I actually downloaded and tried out the app for myself, and I liked it. While an algorithm cannot best a human, this app seems to do a pretty good job at summarizing the news. I think it's feasible - a large portion of any given news article is typically spent expanding on a few main ideas that are typically expressed in one or two sentences. Your typical 1000 word news article follows a predictable narrative structure.

That being said, I found the whole user flow of swiping through sections to be terribly unintuitive and confusing.
