You know what's cool about Siri? Apple now has a vested interest in improving natural language processing artificial intelligence as fast as it can. I don't think there's ever been a commercial interest in that type of technology at this scale before. And they probably have more cash to throw at this kind of stuff than any other company on the planet. I will be extremely interested to see where this develops in the coming years. You can imagine upcoming WWDC events unveiling amazing new Siri developments.

Services like Ixoth may end up being able to develop into much more useful products in the future, once they don't have to rely on hacks like SMS responses.
