The problem with natural language processing and the thing that really holds the technology back, is that when it crashes and burns, it's horrific. I think we would be in a position to really take a serious look at it, once two things happen. The interesting thing about a dialogue-choice system is that we've devoted so much into all kinds of other systems for processing, and dialogue choices use zero processing. So suddenly, if you want to have a great natural language processor, you need to dial down your graphics to make it work.
