Be careful what you wish for. If you can do something sneaky with biological tech for justice, others can do bad things with it too. When I saw the headline with "drone" in it, I immediately imagined an evil plot where some organization genetically engineers a plant to produce pollen with a tailored allergenic effect on one particular ethnic group, then seeds a particular area with it. What's more, they slowly ramp up the level of allergenic effect over the space of a decade, so that the effect looks natural. This will probably be within the reach of billionaires and smaller governments in a decade.
