Information and knowledge is a powerful weapon. Can be used for good and/or bad. Most of the info gathering is sold anyway, for the sole purpuse "of serving you better". That is how you get bombarded with adevertisement everywhere you go. Trying to convince you to buy some that you do not want and/or need. I do not have F-Book or Twatter, those things are non value added crap on my life; full of gossips and ads. Look around you, how many people with their heads down, self-isolated from the rest ("connected" is the excuse); for example, disrupting the workforce. People are becoming nonproductive zombies. What I find interesting is, if you give a diary/journal to someone to keep and then publish it, that individual wil say that is private. If is on F-Book is all perfectly OK to tell the entire WWW all the inner secrets of their shitty lives.
How many of you find convinient to logon with F-Book? To me that is a single point of failure as far security. Someone can hack on your account and create all sorts of damages. In the USA the car insurance company Progressive gives a discount if you place a tracking device on the ODB2 port of your car. The point is to see your driving habits and tracks your commute, record your traveled distnace and speed; GM OnStar does the same thing, but, for a fee to share with you part of the info, for free without sharing. I see no fundamental differences between that device and an ankle bracelet used by people on house arrest. With all the electric throttle, electric steering, ABS, computer control breaking, etc... it is possible to "remote control" your car. So much for security, public safety, etc... that allows the manufacturer to "remote control" your car. All it takes is a good hacker break in to the OnStar system. Can you imagine someone sends a signal to apply the brakes of few cars on a busy hwy. Just enough to disrrupt the traffic flow; or as simple disable all GM OnStar equiped cars on a certain time of the day, let us say... for few hours.
I love technology, do not take me wrong. Technology is a tool, the right tool shall be use to solve the problem. Tech is not the answer to every problem (the meme of "there is an app for that"), if there is no problem, the tech community creates a problem (called "finding a product demand/need").
