It is scary to think how cheap this tech is getting, so semi-expensive things like fridges and TVs will start to come with built-in mobile connections and be always online even if you don't connect them.

With mesh networks it is even scarier, I wouldn't be surprised that at some point even if you don't connect a device like a smart lamp, it might still be sending data about its usage using your neighbors hub.
