As you work on a book, even one as slow to develop as if/then, certain catch phrases develop. People ask you what the book is about, or the shape of its core argument, and some of the descriptions start to stand out and  hit home. One of those is “a world lit by data,” an idea I’ve been toying with for some time now. It’s a metaphor that’s not entirely worked out, but it seems to get the job done – it paints a picture of a time when everything of value around us – everything we “see” – has a component of data to it. In a world lit by data, street corners are painted with contextual information, automobiles can navigate autonomously, thermostats respond to patterns of activity, and retail outlets change as rapidly (and individually) as search results from Google.

The tortured bit of the metaphor is in asking you, the reader, to believe that we will live in spaces full of data, just as we live in spaces filled with light (be it natural or man made). Everyone understands the idea of light as metaphor. But data? Well, to my mind, they are quite connected. Without light, we can’t (easily) take in information about our physical surroundings. In darkness there is far less data. Equating “light” with “data” isn’t too much of a stretch.

Now, the interplay of light and “information” is dangerous but well-trodden ground. After all, in the Old Testament, the first thing God did after creating the physical (Heavens and Earth) was to turn on the lights. And after further contemplation, Christians decided that before Light, there was The Word, which was God’s will made flesh (John 1). Since then, of course, “the word” has come to mean, well, encoded information, or data. Loosely put (and I know I’m on thin ice here) – first we establish the physicality of that which we don’t fully understand, then we bathe it in light, hoping to understand it the best we can.

Given this metaphor, it was fun to see this headline in Quartz: A plan to turn every lightbulb into an ultra-fast alternative to Wi-Fi. The recent “li-fi” spec sends data utilizing the same frequency as light – literally, it uses a light bulb as a carrier of information. Seems my “world lit by data” metaphor is getting quite real, indeed.
