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.
