I am not a technical researcher in the searching area, as a search engine user, I think the Google is very strong and useful, other new search engine may not have much chance to beat the Google in my opinion.
Its really indeed strong and knowing Google its really big and powerful and theres no point on making comparisons between pillar and saying that could become the new Google? Seriously it wont stand a chance. Competing with google is just like that you are punching on a Steel wall trying to break it on your bare hands which we can say its really impossible.
