The document discusses the modern phenomena of data serfdom, where individuals are beholden to large technology companies that collect and utilize their personal data. It describes two appealing aspects of data serfdom - the promise of becoming one's own "Data Lord" by accumulating and leveraging their online profile, and the promise of self-revelation by analyzing the data collected about oneself. However, it notes that the asynchronicity between one's lived experiences and their "Data Self" online is increasing, calling into question the sustainability of the second promise.
