Improving the world's access to information is probably the biggest one? I would guess Google Search is, if you could magically add up all the net positives/negatives, one of the best things to happen to humanity in the last few decades. Having grown up before it existed, I can't imagine how much I would personally pay just for Search to come back if Google all of a sudden disappeared. I would probably give up my car before I gave up Search.
