Instead, I am guessing (maybe hoping) that we see a return of the moderated directories, like Yahoo or DMOZ of old. A 2.0 spin on these directories, with lessons learned from all the years.
Imagine that you just go to StackOverflow and search there directly for your answer. Want a funny laugh, go to your favorite comedy website (like facebook.com) and search directly. Want some news, go to CNN or Fox (depending on your persuasion) and fill your echo chamber.
Not kidding. I think search as we know it is dead. And there is a new paradigm just sitting out there ready for the next generation to make.
A directory of well known lists of websites with specialty search engines available on each.
