I'll be thorax.
Sometimes I wish they would hurry up and invent actual size remote control metal ants.
That way I'd be forced to address the moral quandary of whether I'd allow my son to play with one to engage in one to one combat with actual ants.
In my youth I was unkind to ants. The classic example is taking magnifying glasses to them of course, but I found the Minnesota sun never seemed to have sufficient results, , it would just make them scurry faster. Not to mention, killing one ant seemed strategically useless, I was more one trying to block their entrance, or flood their whole colony, etc. Large scale attacks that might take out the entire organism.
Of course at the time I didn't realize that the ant system was likely a full 4-5 feet deep, with the queen all the way at the bottom.
It isn't hard to imagine a remote control ant allowing a sort of "Ants and Dungeons" type game where you guide your ant down the main sand chute, attempting to navigate yourself all the way to the queen's chamber, ruthlessly dispatching of the soldiers and drones who foolishly try to stop you with mandibles made of non-metal.
However, it seems clear that this is a different type of "killing" ants than stomping on them or funneling bleach into one of their sub-entrances. It seems more personal, and a bit horrific.
Luckily for me, the technology doesn't exist yet, so I don't have to address whether such a thing might be harmful to my son' emotional development quite yet. The down side being the technology doesn't exist yet, so I can't have one and try it for myself...



However, I'd probably be OK if your robo ant could set up a competing colony and recruit live ants to join it.
