I think the ability to share your expertise in video/audio/text format without any technical know-how will continue to be huge.

Everything else is nice but secondary to people being able to communicate, world-wide. Reason being - I think we've solved the food/clothes/shelter technical problems already. What we haven't solved is the willingness to re-distribute the goodies in a sensible way and the way to get there is, is communication.
