The problem is in the explosive growth. The demand for computing power has grown dramatically over the last few years because of the shift to cloud computing and the fact that people are expecting "smarter and smarter" and "more and more" and "faster and faster." If Google had 10x the datacenter capacity, it could (theoretically) crawl the web 10x faster and return more up to date results.
