It is a difficult place to operate from. One of the things that depressed me about robotics for a long time was all the investment in robots that could kill other people.

The logical conclusion though, is you can either own that problem and spend your efforts on developing and making available countermeasures to code that can kill, or you can let go of the problem. In a similar way when you have kids you want the best for them, but at some point you have to let them be the individuals they will be, for good or ill.

Letting go of that which you don't have influence over is, for me, the hardest part of being an adult.
