No worries. I understand where you're coming from. And believe me, I've spent a not inconsiderable amount of time thinking about these issues. I tend to look at raw technology as being "ethically neutral" but it does bother me that there doesn't seem to be any way to truly ensure that tech is only used for noble / beneficial ends. But I don't feel like I can let that stop me from working on tech in general... the only other alternative seems to be to turn Amish or something. And somehow I'm not quite comfortable with that.
