According to John McAfee, N. Korea had nothing to do with the Sony hack.
John McAfee says a lot of things and does a lot of things that seem pretty 'remarkable'. Either he is having one hell of a interesting life, or he is a pathological liar. It seems pretty convenient that he cannot even give this mystery group a name.
North Korea has a well established history of aggressive, belligerent behavior, and this sort of thing sounds right up their alley. John is going have to cough up a lot more evidence than his good word that an agency with thousands of people and billions of dollars in hardware devoted keeping an eye on a rouge nation is wrong.
I'm pretty sure you'll find that meets the definition of 'medical device'.
I think that the thread is getting lost because nerds are arguing over what is or isn't a medical device, which seems sort of tangential to the real question: Is the mood altering effect anything more than the placebo effect? I am a little dubious about the benefits of running a low voltage current into the side of your skull. Wait, lets go back one step further, is there even any medical theory that would suggest that adding additional current to a person's brain would do something positive?
This whole thing sounds like some decided to lick a 9 volt battery and stick it to the side of your head for a healthy mark up charge....
