<human>:  How did the first AIs work?
<bot>: The first AIs were Turing machines, which were essentially just a series of logic gates. The first AIs were created by Alan Turing, who was a British mathematician and computer scientist. He proposed the Turing test in 1950, which is a test for whether a machine can exhibit intelligent behavior. The test is named after him because he suggested that a machine could be said to be intelligent if it could fool a human into thinking that it was human.
