It's interesting to think about but there was likely a time when just about everything in your home was considered revolutionary and new. Depending on how each tool and device you use came about, there may have even been some people who thought it was a crazy or dangerous idea.
For example, most of us simply see a train as a means of transportation now but people once worried that they went fast enough to make a woman's uterus fly out. Obviously, that's not a problem we have to worry about.
But while I doubt anyone is making such an outrageous claim about anything we'll see on this list, we also shouldn't be surprised if we see them much more often in the future.
