Beyond Search provides a quote from neuroscientist Gary Marcus about search engines that appeared in Explore:

Forget search engines. The real revolution will come when we have research engines, intelligent Web helpers that can find out new things, not just what’s already been written. Facebook Graph Search isn’t anywhere near that good, but it’s a nice hint at greater things to come.

Will Facebook’s new Graph search lead to big changes in search?  According to Explore, the quote also “echoes Vannevar Bush’s 1945 vision for the future of knowledge.”
