We seem to have an ingrained cultural notion that technology solves everything. Got a problem? Throw some tech at it. Is that problem still there—or did it get worse? That’s okay. Some more tech should do the trick. This is what the wearable tech corporations like FitBit have been telling us. Wear a wristband that tracks the amount of steps you’ve taken, or the calories you’ve consumed, and that’ll make you fitter. Which launches us into a serious dilemma: we begin to think that we have control of our fitness like we have control of our thermostat.
Just change the little number and the temperature will change. The little number says how fit we are. But the body is a complex system, and as such, it is hostile to our attempts at simplification. If we try to “describe” fitness in such a simplistic way, we will find again and again that we are becoming overtrained and injured. As Albert Einstein said:
“Whoever undertakes to set himself up as a judge of Truth and Knowledge is shipwrecked by the laughter of the gods.”
That is exactly the claim that wearable tech purports to let us make: that we “know” how fit we are because the little digital monitor says so. We can say “this is our fitness”—a claim about knowledge (or even worse “this is fitness”—a claim about truth). And our bodies, and our fitness, will be shipwrecked accordingly. The gods will be laughing at our disdain of the fact that the body is a dynamic system.
