By 2020 the camera will be surgically implanted in our skulls and will take permanent images using our eyes as lenses, and our brains for processing. We'll have built-in USB ports to connect to a thumb drive or a printer...

This one is it. Almost.
Camera gear updates will be implants of some type. Long lenses will probably be glasses or a spectacle of some type. Crazy long lenses will be devices mounted to something other than ourselves with wireless connections (lens pools, shared security cameras, satellites, telescopes (like the Hubble)). Printing will be gone. It almost is now. Hand held devices will replace paper. Up links to hosting sites will be instant and I'd even bet the active billboards will be used to display things (you know, like the boards they had in the movie Blade Runner that everyone said would never become a reality but now they are everywhere). Everything will be wireless. Even power. Look at the wireless power test beds they have now. Amazing work. They are powering 60 watt light bulbs without wires across rooms now.
It's going to get crazy!
Will I be here in 2020 to see it? Not a chance. But if technology can make some huge leaps very soon I just might be able to last that long. I could use a couple of replacement parts right now...
We also need to find a way to stop an object in space from hitting us. Right now we are still in the "very" lucky category of the game. We also need to find a dependable way to get off of Earth. If we spread the human race out, we stand a much better chance of survival. Or maybe we are such an insignificant being we aren't meant to get off this rock and the distance away from everything else was part of the plan? Hmm...
And if we toss the whole aliens visited earth thing into the mix. What will happen in December of 2012? Does the world end? Do the aliens come back for another visit? 
Jon.
