Hmm, promising, but I think in order to really "use" those, one would have to increase their size -> capacity, which would come at a hefty price tag.

While the batteries in the picture and article are low power/long life batteries, it's only a matter of time before the Wh/kg of battery tech reaches a point these drone swarms become feasible.

On the bright side there's money to be made developing personal low-range EMPs or similar for defence, but that's another can of worms.

What possible future (technological) breakthrough might be a grave mistake?

Thanks, but i'd appreciate some more comforting words, too. 

Also, can we get some additional info on the pic?
