Answer:
Artificial intelligence is the intelligence or logical reasoning exhibited by artificial devices, as opposed to natural intelligence exhibited by humans and animals.
The main threat that artificial intelligence poses to humans is not, as many fantasize, the possibility of a future apocalyptic scenario; but the very limitation that artificial intelligence makes to human intelligence: each time the human atrophies his capacities more, since he relies on artificial intelligence processes instead of using his own. A clear example is the GPS, where the human no longer has to exercise his memory to know a path, but simply depends on what the map tells him in his car.
