The structure Han and Pritchard used is good for most demos: An initial tease Necessary background, context, and/or the invention story The demo itself (the more visual and dramatic the better, so long as you’re not faking it) The implications of the technology Sometimes a demo is stunning enough that it allows an audience to imagine truly exciting applications and implications. And then the demo becomes not just a demo, but a vision of the future. That’s where we turn next.
