Already computers can beat Humans in games like chess.
Unless a way can be figured out to program such things as ethics into the machines programming and a 'fail-safe' to prevent it from getting out of control - The machines will attempt to, and probably succeed in taking over.
At that point it may use Humans as slaves to service it - Or, it may decide that biological life is 'dated' and no longer necessary.
Sorry, but we must consider 'worse case scenarios' before it is too late - There are computer scientists, and men such as Bill Gates, and Elon Musk who have also expressed this view.
