Author Carl Miller doesn't recognize himself from his aggregated data - not surprising, given that he is characterized as "young and struggling", no "regular interest in book reading", and a "Netmums - women trying to conceive". So, OK, the technology that collects data about us hasn't fully matured yet. But should we be cheered or spooked by the prospect that it will eventually get it right? Even more concerning, it is difficult (and getting more difficult) to know how these companies are depicting us. Whether or not they get it right, we should be able to see the data. This data will be how employers assess our competencies and credentials in the future; companies that collect and create this data have an obligation to get it knowably and openly correct.
