When I was a teenager, the future was the Babel Fish. A fictitious fish that could be inserted into an ear to deliver translation from any (galactic) language.
Later, with typical geek humour, we had babelfish.com which was clever but didn’t offer real time translation like its fishy namesake.
It’s not quite a fish you stick in your ear, but this is truly the future. I can’t wait to see how these work, and whats next.
