The future is bright for complexity

"The future is bright for complexity." - David Seuss

From the same presentation -

"The ultimate future - Personal Search Engine
- Setup your personal content set from all the sources you know about as a result of your professional life
- Searches that contentset just for you !"

Thinking about it this definitely makes, Google will have tough time adapting the result set to the unique user context (there's a model of generalization) and thats where specialized/personalized search engines will be more effective.

I would love to see a personalized search engine which builds out a private Google based on three user inputs -
resume (professional associations and meta-data for skill/technology proficiency)
bookmarks (professional and personal interest destinations)
and blog (professional and personal interest discussions)
