For one example, If I want to take a holiday, could an assistant work out the best dates (based upon preferences of availability, cost etc), and research the best airfares (excluding that particular airline I hate) and find a hotel room with the features I want, and throw in a few sightseeing activities which appeal to my personal tastes, then summarise it up into a travel itinerary for me to approve. Then, upon approval it proceeds to book (and pay for?) all the things.
