Whoa, I didn't say this is suitable for predictable business applications yet! What I did say is that I'm in awe at the fact that this stuff works as well as it does, given that natural language is so notoriously prone to imprecision and ambiguity. I mean, if you had told me six months ago that this would be working even "95%" of the time in demos, I would have said, no way. Basically, I agree with you that at present this becomes "less suitable the more you move away from demos to predictable business applications" :-)
