If you seriously believe that it took minimal engineering effort to integrate those parts into a low latency real time system I don't know what to tell you. These kinds of dismissive comments on HN never cease to amaze me.

Well, yeah, but without that google_translate part, they wouldn't get nowhere.

Bing Translate, even though it's been used by default on both Facebook and Twitter, will probably never give you good enough results to have a conversation with a stranger. Google Translate probably will.

I mean, if there's anyone that combine those couple of parts, it's Google and no one else.

It is remarkable because it happens in realtime.
