It can manipulate inputted data and create a response. Obviously they haven't answered there own question, the computer has. This has nothing to do with the computer, the computer just proved an answer, thats as far as the interactivity goes. The difference is who is in charge of the interactivity. There is no more to it than a user interacting with the intelligence programmed into some piece of software.
Computers essentially store and manipulate data.
They don't create anything, they manipulate inputs. The user inputs, the computer responds.
