kinect was the one of the first device to sucessfully use natural language processing for controllerless entertainment which already works pretty well in the context but MS never thought of probably extending and integrating the tech with other products.

Strong point of MS was integration of different technologies but ever since Gates stopped taking interest in MS they have lost it. Now they have uncapitalized half assed implementation of technology laying around in silos.

Note: I am well aware of when Gates stopped working with MS. Even before stopping to work, he stopped taking interest in MS's future vision atleast years before that.
