A super intelligent AI is not necessary for AI to be an threat. Dumb AIs that are given access to the internet plus a credit card and told to maximize profit could easily cause massive damage. We are not far from such an AI being accessible to the masses. You can try to frame this like the gun debate "it's not the AI it's the people using it" but the AI would be acting autonomously here. I have no faith that people won't do extremely risky things if given the opportunity.
