@david_chisnall I'm not so sure. I often express myself in natural language to ask people to do things, and that usually works out pretty well.
So it's possible in principle, it's just not something that computers can do yet. Maybe one day they will.
@jarkman When I ask people to do things in natural language, it often fails miserably (the people do the wrong thing). You must be interacting with very capable people or your natural language is very precise and unambiguous.
