I think Google is one of the few companies that are able to start building the internet of things, with all their server farms, smartphones, TVs and some self-driving cars ;-).
Then you no longer need to query Google's search engine for timetables or nearby shops and restaurants. The internet of things just tells you everything you need to know.
It is really interesting which technologies will clear the way for the interconnected mesh of systems. Thereby Erlang will hopefully find its way to more and more backend systems :-).
