Yes, the problem won't be solved completely and you will still end up reading the same content more than once. But at least, by analysing the text the search engine could detect which articles are coming from the same source (e.g. inspired by the same press release or just telling the same news event over and over again) and group them accordingly. Currently, I don't feel like Google or other search engines are doing any of that (maybe they are, but if so, the results are not good enough).
