Search engines providers are waiting for billions of dollars to have some of the smartest people in the world working to develop the next great version to enhance more relevant results.
Satellite and aerial imagery are these days the main attraction (Google Maps, Google Earth, MSN Virtual Earth, TerraFly, World Wind, from NASA); this is the stepping-stone to real-time and interactive imagery from space. Real time, high-resolution images delivered over the Internet, showing details such as backyards or streets are the present and the future for the main search engines.
The search engines are getting smarter and more powerful. Such complex and powerful searches will be practical in three to five years when computers are more powerful.
