Okay, it’s a mask, but as far as I can ascertain, this happened. One imagines the CIA is happy to leak disguise technology from 30 years ago. Who knows what they have today. Of course, donning a mask does not infuse a person with language skills or cultural empathy. For that, you just need to hand a suitcase of cash to a person who grew up in another language and culture. The only thing that might have changed about that technology is the suitcase.
