Fishtanks are useless
The Internet of Things is pure hype. Not only is it a solution out looking for a problem, but it will never happen. My TV, stereo system and blu-ray player can't talk to each other. And now my TV refrigerator and coffee machine, all from different vendors, are supposed to be collaborating? A network is not enough. You also need protocols that are open, properly implemented and adhered to. Unfortunately protocols imply architectures, and requiring a certain architecture can be constraining. Companies tend to retreat into closed protocols, but this forces consumers to stick with one brand, and they almost never do so.
