narrowed the gap between Gmail and Search, thus demonstrating that whatever distinctions currently exist between Google's various services are only temporary. The walls are coming down, and we are ever closer to having just one Google.
To be clear, I'm not saying that Google will no longer have multiple sites and apps that do different things. Google will continue to have multiple services (like Gmail, Search, Google+, Android, YouTube, etc.), because people prefer apps that do one thing well rather than many things poorly. However, we can no longer think of these services as distinct products. Rather, they are all windows into the big pool of data and algorithmic prowess that is Google. In other words, there will be just one Google, but many different ways to access it.
