I had a similar thought partway through writing my critique. I think that, given how close wearable computing seems to be getting, it's definitely worth pointing out things that don't work, even if they're a metaphor for other internal processes.

It would also depend on how the drone's AI is implemented. If it's based heavily on imitation of a human mind, overlaying data on the optics might well be the best way to get stuff like that in. Or if this "drone" is actually a Robocop-type brain in a box, as PayUpPal suggests.
