Moore's Law and other advancements will continue until all our cameras capture constantly. The biggest advancements will be near-infinite storage and very fast wireless cloud uploading, as well as great new methods for quickly scrolling through pictures or video to pick the ones you want to save.

Instead of "taking" a picture, you'll instead just pick one from the gazillion pictures already taken.

Wearable computers like Google's will create new opportunities for photographic memory, as you'll be able to simply "rewind" your own life at any time and catch the instant replay.

Cameras that take "still" photographs will become obsolete. They'll all take video and, like the 4K camera, ordinary consumer cameras will take video in which each frame is a high-resolution still image for the taking. Instead of trying to "snap" the photo at the perfect moment, you'll record video and pick the right moment later.

So get ready for a future in which cameras never stop taking pictures and video. And smile: because you're on constant camera.
