I'll gladly take those threats with the benefits that will flow from the technologies needed to create such things.

If you can make a nuclear reactor for peaceful purposes, you can make a nuclear bomb. If you can make a knife to cut meat, you can make a blade to kill your fellow man.

You can't have things that can be used for "good" without things that can be used for "evil".
