Big data is junk
Companies have started to admit what we already knew, that "big data" is overwhelmingly junk.
That's the deathknell of "big data" as the buzzword du jour, and really the whole concept of smart anything. Fill your city with sensors, and you'll collect mostly noise which will allow you to do precisely nothing.
And even if any of it was useful, the solutions would have to be built in at the planning stage of a NEW city, which is so rarely the case except in still developing nations.
