What's going to be the next big thing?

I was watching CNN the other day, and some dude was talking about how we will one day have chips installed, to help us deal with diseases and whatnot (needless to say, I was all “whoa, that’d be big”). Now, I don’t think that’s going to happen anytime soon (‘cause I’m still waiting for my flying car), but it got me thinking, what’s going to be the next big thing? That? Something to do with energy? With the weather? With our food? What do you think?
