This just remembered me about the MIT system created by Terry Winograd in 1970 called SHRDLU. I have always considered that you need an environment to create an artifical intelligence. The basics for a real progress are to be able to learn and if you cannot 'feel' the environment that becomes really hard. There are some basic concepts needed for a 'natural talk' you cannot learn if you cannot perceive things (lets say for example dimensions, temperature, contour). To overcome those problems SHRDLU created kind of a virtual environment and results from my point of view are really awesome (keep in mind this was done in 1970).
