I really like the comparison of Google to gravity, because it implies that Google is a critical component of the nature of the internet. The problem with Google is that it is only a service of the internet, not an integrated part of the internet's structure. We expect the internet to have a search feature because everything has a search feature, our operating systems, our apps, everything. We expect the pages on the internet to be indexed and organized because, hey, everything else is too. Unfortunately the internet doesn't have any of these features built in. Google is just another website just like every other website, and it's limited by the same things that limit every other website application. Using Google to search the internet is like using a third party app to search your Outlook emails (if you have billions of emails). What Google, or any search engine, does is ultimately flawed by the technology it's built upon. If the internet was created today from scratch it would no doubt be engineered to support indexing and all of the other things that we take for granted, so third parties don't have to hack their ways around billions of individual html files.
