The Google search bar has become iconic in the online world. Other search services exist (Bing, DuckDuckGo, etc…), but Google has eclipsed all of these with their powerful and ever-evolving search algorithms and machine learning.
What Google has effectively done is make the massive and varied Internet a digestible and easily consumable thing for all of us. Without the ability to search and segment, we’d be endlessly lost in the deluge of information. Google makes the huge and imposing manageable. And more than that, they do it better than any other service.
