Not too long ago I wrote an article about this specific issue regarding larger scale drones. Today these amazing entrepreneurs have developed a drone modeled after a Dragonfly.  At first look the technology is wonderful and amazingly cheap ($119.00).  Nothing can bad can be said about the amazing work these guys are doing to better drone technology, robotics, and tech in general.    

But with the good comes the bad:

It is hard to contemplate the immense privacy issues concerning this and like products.  For one, they are almost unnoticeable (unlike massive Predator style drones).  More importantly they are much more accessible to ordinary human beings.  The results of this social experiment have yet to be determined.

Until that point comes, kudos to the inventors, and the investors.
