There are always two kinds of developments. One is where you have a huge problem and people try different things to solve it. The other thing is where you have new capabilities and don't know yet what to do with it yet. One is not worse than the other. Given some time there will be reasonable usecases. Think back to the first iPhone and Android. Nobody really knew what to do with a smartphone yet. Now everybody has at least one and uses it way too often. Internet of Things are just one of the next areas. Let's just calm down and let the market work out what's reasonable.
