Do you think AI (artificial intelligence) is something to be feared?

I'm having a hard time thinking of a situation where a bomb in a driverless car can be more damaging than a parked one.

I think that is somewhat like saying we shouldn't build roads because that could lead to easier car bombing or we shouldn't build cars because that will make horse bombing so much easier. Sometimes we ignore all the potential benefits of something because of a fear that something else might get infinitesimally worse. I'm sure someone will eventually use a driverless car as a car bomb, but I don't spend a lot of time worrying about the extremely infrequent car bomb as it is and it's going to be a while before driverless cars are cheap enough for bombers to consider them disposable.
