Is There a Future for Technology?

I like the example of em you know, that in te future, everyone's going to dry their hands with like, hot air. But it's just got to be done in a way that looks futuristic. We're still building stuff basically out of the same five or six most common materials that were in use thousands of years ago. If things work, we don't change it just to change it. You know, there's got to be some kind an advantage to it. The whole package has to be worth it.
