What about for communicating visual information? I can visualize imagery and "animations", but I'm abysmal at graphics and could never adequately translate it to another medium like paper or image/video editing software. But maybe if I can transmit it to someone so it's as clear in their mind as it is in mine, that could greatly increase information density and express things that otherwise can't be compressed into language; perhaps not even some future "neural intermediate language", either. A picture is worth a thousand words and all that.<p>Being able to transfer it from my brain to a digital medium would also probably be almost as good. It'd also be amazing if you could do the same with music; compose and "hear" some music in your "mind's ear", then have it be rendered as MIDI or full audio. I'm sure we're very far away from things like that, but if they do happen, I think we'll look back and wonder how we possibly lived any other way.
