What is the Next Big Thing?

This is a silly question to ask on some level since anybody out there who could answer it correctly would be too busy getting rich off of it to waste time idly perusing the internet. Regardless, I can't shake the feeling that with the possible exception of the internet (and before that, the home computer) there hasn't been anything new lately. What passes for new technology these days is almost inevitably an improvement, be it incremental or exponential, of some extant technology. Things get faster, smaller, and cheaper. We get more and better ways to waste away our lives staring at movies, games, and the internet. Medicine gets a little better at treating what ails us, cars get a little faster, food gets more plentiful (and imperishable, although we dare not ask how). We have conquered instantaneous global communication and the cheap mass production of any imaginable disposable consumer good (turns out the key ingredients were Slave Wages and complete lack of regulation).

I'm not bright enough to think of anything actually new, here are my best guesses at the next incremental steps forward that will make someone who isn't me a multi-billionaire someday:

1. Cheap, safe wireless energy transmission. Recharge electronic devices (not to mention electric cars) without plugs, cords, or wired infrastructure. We've already taken some baby steps in this direction with charging mats, but whoever can invent something that allows you to charge your phone and laptop just by walking into a building is going to print money.

2. Non-brittle carbon fiber / composites that can replace steel. CF was hailed as a revolutionary breakthrough back in the 90s, but unfortunately despite being extremely strong it is also brittle as hell. Whoever overcomes that problem will have a material that can replace metal and masonry in buildings, vehicles, heavy machinery, prosthetics…

3. Doing away with the physical interfaces between us and our various computing devices. I have no idea how this could work, but eventually someone will find a way to make this sentence appear on my computer screen as soon as I think it. The keyboard and my fingers will be superfluous.

4. Artificial organs that are improvements upon, not just replacements for, the real ones. Any significant further extension of our lifespans will require either some way to stop aging (unlikely) or organ replacements that last forever and perform even better than the ones nature gave us.

5. Online smells. As stupid as it might be, someone's going to find a way to do it and then middle schoolers texting each other farts is going to be a billion dollar per year industry.

I'm not very creative, as you can see. I bet you can top these.
