We now ask the question, ‘What will happen when a machine takes the part ofA in this game?’ Will the interrogator decide wrongly as often when the game isplayed like this as he does when the game is played between a man and a woman?These questions replace our original, ‘Can machines think?’
This is an important sentence in the essay because it explains how the imitation game works and how a computer will be incorporated into it. The computer will take the position of player A and will try to confuse the interrogator, so they don't know who is who.
