I believe authorship is one signal that a search engine may use to determine the value of a site. I very much doubt that in the long run, anyone can expect to rank high simply because they have Google Authorship. If you are a recognized expert in your field, AND you have authorship, this may help Google weed out people who throw up websites to further pollute the web. I see Google Authorship as a work in progress with a bright future.
