For obvious reasons, SEOs are fearful of this shift, but it is, in fact a boon to the industry as a whole over the long term. Imagine being manually ranked in the top 10 for an exceptionally popular search term. The only way you can lose rankings is if the quality of your site/result deteriorates in comparison to the competition. Instead of link-building (which I personally find boring & distasteful), our jobs would be primarily about building the best, unique content available for the subject. That sounds like a switch I'd be happy to make.
