I'm sitting in the first session of Supernova Challenge Day. The discussion is about the new semantic web.
Nova Spovack from Radar Network just talked about the fact that in the future voice will be the main way to access the web.
This is a very important thing to think about. When you ream the reviews Powerset gets today, you see that Google actually still gets better results a lot of the time. But when you think of voice, the ability to actually parse the meaning of a sentence becomes much more important, as people won't search by simply saying words, but by saying complete sentences.
If Powerset will be able to actually understand meaning, they will be bale to be the future gate for the Internet.
