I consider search an essentially solved problem and I think most people agree with me. When I want to find something I can usually use Google or Bing to get to it within 10 seconds or convince myself it doesn't exist. Will search get better? Probably, but going from 99% to 99.5% isn't very exciting to me.

If anything, I see Google and others moving in a direction of using context to reduce the amount people search (e.g. google now). I think this pattern is going to get much bigger in the coming years with better AIs and more information about what the user is doing.
