There are a lot of other technical questions that can be asked, but those can’t top the ethical ones. Can’t they be used as hidden-surveillance by the government? Will we turn insects into weapons? And then there’s the question of disease-carrying insects or using insects to disperse chemical weapons. How should it be regulated? Where is the line drawn? My personal opinion would be to leave the technology at looking for victims of a natural disaster and as surveillance for the military during wartime. Leave chemical warfare out of the equation and do not target civilian targets.
