Real-time translation is the type of technology that has practical implementations. I could care less about finding designers on LinkedIn via a voice command. But if I am stuck somewhere in another country and unsure where to go or how to communicate, I guarantee I will be happy to have that translation service available.

Here is an idea for a service: You lease the translation service for the term of your trip for a dollar a day. You can lease on demand for 24 hours for 5 dollars.
