I am just amazed at how far, and how fast, this technology has come in
such a short period of time. I try to keep up with technology but
this one has caught me totally flat footed. Absolutely astounding.

I think the general public is still way behind the curve on this but
will probably start becoming aware very soon. That is not a good
thing for hobbyists in my opinion. Much like when the general
population discovered the internet back in the late 90's, there will
be a lot of anguished cries about how awful this all is, and why
aren't there any laws, regulations, etc. My advice is to buy what you
want as soon as possible because within a year or two we will see
groups called "Mothers Against Remote Video Cameras", "Mothers Against
Quadcopters", etc., plus a lot of calls for legislative action.
Meanwhile law enforcement agencies will start using them in droves and
people will start getting arrested for taking a whizz against a tree
in a wilderness area. These things will probably end up as highly
regulated as handguns.
