It’s been long enough for a comeback.
It got ‘old’.
WAS: Instant pictures? BIG DEAL – we had DiGitAl na0
IS : Digital pictures? BIG DEAL – we want something we can touch instead ‘just another digital picture.
It’s because what’s new “got old” and what’s old “looks new”. I’m still waiting for instant 3D camera/printers myself. We’re not far away from it.
3D live scanning will soon be mature, where you can scan with your kinect-type thing on your phone (they’ll all have them in a year or three) – Google’s Project Tango is just the first of what’ll be many – , where you can make a Minecraft-like model of your reality around you… and then it’ll Bluetooth (or some faster wireless) to a 3D printer with cheap colored resin balls so you can have an instant model of… well, whatever you take a picture of.
So instant cameras are a necessary part of the next stage – remembering where we just were, to see where we’re going in the next few years.
