..........or (d) there are doing a multiple level survey to determine new product implementation. I think that although nefarious objectives are possible, it is equally possible that in a new-er technological age that there are companies who are trying to think up new improved products and services based on our actions from a macro perspective.
I recall the days when time analysis people observed the workplace to access strengths and weaknesses to enhance efficiency resulting in better margins, just a different way of thinking about this "invasion of privacy" in a different time. It occurs to me that so much these days has become a double edged sword.
I believe it was Farnsworth and someone else who developed the ability in the late 1920's and early 1930's of radio finding a way to determine the effectiveness of their broadcasting...without it, stations would not have been able to sell advertising and get the much needed revenue to build an industry..thus putting people to work.
So, while not denying the basis of concern over this tracking, in a greater general sense I believe we are merely witnessing that which in greater numbers represents the future...the service industry...which in turn dictates the manufacturing (little in America albeit) done in the world. I am thinking that just as "just in time" logistics are now the norm...the same is true of the other side of the equation. This is the child or grandchild of early time analysis.
Especially so in a "new normal". It sounds kinda funny to say this...but the first time an early caveman was asked when he would be back...he probably didnt appreciate the intrusion...lol
