To be honest, I did not get much new information from this reading. It talks about the phenomenon of the digitalization of everything in the second Machine Age and how the large and comprehensive database and the almost free nature of reproduction of digital data have completely changed the way we do science, invest in real estates, find our way to work and so much more.
On the other hand, the availability and size of data are so powerful that, if used inappropriately, could be very damaging. For example, many personal data have been used by companies like Cambridge Analytica to swing elections and place ads.
