From a consumer perspective, it's less flashy, I guess. It's helped me figure out things that I can't find on a search engine, but that's not quite as big. From an engineer's perspective, all the tech for Google maps existed at the time, and for certain users accurate GPS with maps was already an established thing in 2000. On the other hand, we'd been trying to do anything useful with natural language since the 50's and had thoroughly failed.
From a business perspective, being able to lay off every order taker at your restaurant chain (and maybe the middle managers and bookkeepers too) is huge. It's obviously huge for order takers, and it's pretty big for the restaurant owners and anyone who eats at restaurants as well. I think that qualifies as "eating the world".
