Fascinating & eye-opening documentary exposing & explaining how our digital data is mined, collected & abused in order to create individual & demographic profiles, & then use targeted ads in order to manipulate our emotions...
This would be bad enough (but not really the end of the world) if it's merely influencing our shopping habits (& don't pretend it doesn't work, otherwise it wouldn't be a £Trillion industry every year), but what happens when companies like Cambridge Analytica use this (illegally) harvested data to influence our voting in elections around the world to suit the highest bidder.
If you claim none of this ever influences you, then you simply don't understand it.
Highly recommend watching (it's almost like a Black Mirror episode, which is depressing).
