Imagine being able to go anywhere in the world and communicate. Imagine being
able to visit a village in northern Laos, pull out your phone, and have a
conversation. Or imagine being able to make a call and have your phone do the
rough work of translating on the fly. It would need to do many very difficult
tasks simultaneously to pull this off. It would need to detect the languages
being spoken, understand them, interpret them in real time and translate them.
