I think the PTB are rolling out tech for two main reasons:
1) capitalism
2) surveillance
As for how to deal with the information overload: one must create a healthy diet not unlike dealing with the Western food overload. Find sources of the good stuff, and don't overindulge.
Totally agree with the second bolded part. I like the sum of your post, but I would question this idea of the 'powers that be'.
It's interesting - a goodly portion of those on this chat site (I'm not saying you, Soupie, just talking in general terms) seriously question the idea of soul and spirit, and even, oddly enough, psychic events. (A good dollop of cynicism is not a bad thing, imo). However, those self-same people will posit that 'powers that be' - or elites - have prescience of a kind that I - who very much endorse the existence of soul and spirit - would never ascribe as a matter-of-course to anyone, least of all groups, who are notoriously dumb when it comes to insight.
Hindsight is always 20/20, as the saying goes, and one can always squirrel away into the past and find nuggets hidden here-and-there 'in plain sight', ignored at the time, but with subsequent knowledge of trends one sees as pivotal. The 'powers that be' - like an Al Gore - may have added insight due to study and access to heavy-hitters (thinkers) - but Gore's synthesis is nothing that is not available to anyone inclined to do the same study. (Just look at his bibliography - all his notations - to see the trail of breadcrumbs he followed).
Capitalism is 'eyeless in Gaza'. It is Samson chained to the pillars - and it will pull the temple down around our heads 'without passion or prejudice'. The whole 'mechanism' is driven by individual choices of both survival and greed. The 'powers that be' can control it in only the broadest sense if it isn't already controlled by the government overtly. But as Gore so aptly phrases it - 'democracy has been hacked'. (His analysis of governance is particularly insightful imo).
As for surveillance - that is a two edged sword. Even Gore says as much. Such surveillance is a deterrent - but to think that any of it means anything more for each of us beyond the occasional crazy (in the surveillance structure) who decides they want to monitor someone in particular, there is little use for keeping tabs. There isn't enough man-power to make use of it for any reason - except as Gore suggests, for buying and selling.
This weekend we went to see the documentary
Finding Vivian Maier - unexpected, we all agreed. Hard to say what we thought we'd see - probably something innocuous but charming - not something as dark and strange as it came to be. But there it is - the hoarder, the obsessively private, the paranoid view that one is being watched. Take that writ large. One has the problem any 'power that be' faces trying to control a mass of people - people are unpredictable, and often crazy in unexpected ways. There is the fact that one can trust an animal to behave like the animal they are - but not if a particular one is sick, injured or in pain. With humans it could be said that most of us are, in some measure, sick, injured or in pain - or can be placed in those categories very rapidly through adroit means. That said, none of us can be 'trusted' to behave in any way - even aberrantly - because even those subjected to those stresses can make other choices and defy the statistical odds.
The idea of elites that make overarching decisions knowing precisely where and in which direction such decisions will head us just doesn't stand up imo.
