I mean the Internet brought us all so much closer together than ever before; technology like this will make us even closer, if we can do better/perfect translations it means that we could be interacting with people in English who are native Spanish speakers, for example, without even realising (on the Internet, at least).

And it's tough, because if you like travelling, it's not really feasible to learn every single language for every place...but in the future if I can pop an earbud in & get a realtime translation & they can do the same, I'd probably speak to so many more strangers when I visit non English speaking countries. It'll be so great.
