The debate over communications rages on much according to Tim Wu’s argument in his best book from some years back The Master Switch, and more narrowly made in technically oriented books like Who Owns the Future? by Jaron Lanier and another one I read in the past called Dogfight by Fred Vogelstein about the Apple/Google battle which essentially argues that whichever is on top—these two companies own modern media and communication.
Progress in the software and technology that drives not only communications but also much if not most of the rest of current human endeavour, whether industry, transportation, government itself, is something which continues to be vital to understand for someone involved in technical communication.
And more recent books like Privacy is Power by Carissa Véliz, which deconstructs how our most intimate data is aggregated by the big tech companies and others to basically manipulate us, is another great primer.
