Before you say something is breathtakingly wrong you should read it carefully and try to understand it. This way you might also get some of the jokes that are currently flying over your head.
The bit that is breathtakingly wrong is the notion that you can just take some smart lisper, lock them in a room, and have them replicate what ITA did and have that be a viable business. See martincmartin's and my comments later in this thread to learn why that would be incredibly hard. With a smart enough team and enough time and money, you could certainly do it, but this is a project that would take many years and its unlikely anyone would be able to keep funding for that long. ITA had a much easier job: it was competing with very poorly designed systems that ran on mainframes and had very little CPU power available.

From what I hear it worked technically, but failed commercially due to the badly timed recession. It seems like a fair bet that Google's offer wasn't putting a lot of value on the reservation system. Even if it could be made to work, it's not the kind of a business that Google is usually in.
