What you've said is true about ALL new technologies.

More people were killed by motorcars than by buggies; obviously the internal combustion engine was a mistake. Airplanes can crash from great heights: mankind obviously wasn't meant for altitudes in excess of the nearest climbable mountain, and ALSO: bombs. And no one was ever electrocuted until mass electrification occurred; piping lightning directly into our homes is just asking for fires.

Movies are awesome! Also, they can be used for mass propaganda. As can that dang printing press. No printing presses, no Mein Kampf, so maybe that ought to be looked into.

My point is that yes, all new technology has a potential for causing damage and for being misused. We should definitely be conscious of those things. But that doesn't mean we need to stop development. What we need to be is aware.
