The people who start self-tracking are successful and have nothing to lose. If you can self-track and prove you are better than the average person – are healthier or drive more safely – you can get a better deal and claim some benefits. Yet eventually we will reach the point where people who decide not to self-track are assumed to be people who have something to hide. Then they have no choice but to start self-tracking. Very often the people of Silicon Valley who promote these technologies say we have the choice, we have complete autonomy, and I am saying this a myth.
