...In other news, I actually developed what I think is a neat idea for a universal translator. It wouldn't work for visual or pheramonal cues, being purely off of spoken (and written) language (and maybe other sounds that aren't strictly speaking, but still classify as communication), but it'd work something like this:
A cybernetic implant using advances in microchip technology, embedded into the brain. Working off the idea we 'think' in a language, it'd take sounds and translate them into the user's base language (using a built-in library), effectively filtering noise to allow for understanding. Then, to respond, the computer would use its understanding of both languages to tell the user how to say what they're thinking, in the target language.
Might not be perfect, but seems cool!
