People to just create lifelike videos of anything they can put their mind to, is bound to lead to the ruining of many peoples' lives.
As many people that are aware and interested in this technology, there is 100x people who have no idea, don't care or can't comprehend it. Those are the people that I fear for. Grab a few pictures of the grandkids off of facebook, and now they have a realistic ransom video to send.
Am i being hyperbolic? I don't think so. Anything made by humans can be broken. And once its broken and out there, good luck.
