The fact that this alone has changed into "type something into Google, get back relevant results in milliseconds" has already changed the world. (And yes, I know there was Altavista etc as well; but there's a reason Google won the search wars.)
Also, compare these two for kicks:
Google's mission is to organize the world's information and make it universally accessible and useful.
Goldman Sachs: Our goal is to provide superior returns to our shareholders. (http://manonamission.blogspot.com.au/2005/07/goldman-sachs-g...)
I can see the logic in that if that was entirely true. But I don't know if I can agree that either Google or Apple's particular takes on various high achievements were actually inevitable at all (search in various forms, and maybe not the PC, but the iPhone, certainly).
The originality most people see in Apple's products doesn't lie exactly there. The big thing about the iPhone was the battery life and the hard disk. Not the touch screen interface. A touch screen interface was easy to make and copy for Google, that's why he did so quickly.
Indexing large amount of information (what google does) was or would be a requirement in the years to come. A solution that would be begging for an answer. At the time, no one could foresee how a good indexing vs bad indexing will shape the internet. But a few years later it was clear that we're heading towards big data.
Now, I firmly believe that stopping starvation all over the world, with today's technology is entirely possible. I also believe that this would change the world for the better in a much more meaningful sense. Technology today allows to create abundance, but our society chooses to create virtual demand, where possible.
