I hope to see them inventing a great development environment for window, Linux, and Android that is as good or better than Visual Studio with C#. I hope they can invent and be creative rather than stealing technology from Sun and Microsoft and Apple. If they can do this, then they can read my email and show me advertisements as much as they want. I don't see much that google offers other than advertising my products on searches which really puts them as a media company more than a tech company.
They bought Nest and some other tech products but what are they doing with them. They will do stuff like show you a hot tea product you can buy on sale when they know it is cold outside by you. Again, all advertising and media. Soon they will know more about us and our needs then our closest friends and relatives. With their set top box, they will be able to target advertising based on what you like to watch, where you surf on the net, where you go by tracking your position on your phone, who you talk to and send email to, and what your home is like. This could be a good thing or bad thing. It is creepy however.
