Natural Languages in Programming Languages

I think natural language in applications/and programs are a great idea and are a move forward from unintuitive commands that are hard to remember. They break down barriers between user and application, communication is improved both ways and users feel comfortable asking a simple question rather than working out the correct command to get their answer. However the drawback is though that even though there is more communication there could be a lot of misunderstanding and ambiguity, and vague requests will need to be interpreted and handled properly by the system.
