Identity theft, computer hacking, customized consumer advertising, and personal data accumulation, by every company we do business with, has become a part of every day life as tying our shoes or going to the store.
Billboards have facial recognition and can change what they advertise to appeal to whoever is passing by them at the time. Every institution from Amazon to social networking wants us to store all our personal information on one of their computer clouds. GPS in our cars and on our phones can locate us at any time. Google watches and stores what we look at on line. Medical records, tax records and employment records to name a few, are also on line.

Over half of all stock transactions are executed in milliseconds, not based on fundamentals, but on an advantage in speed that technology makes possible.
* Also known as ten quadrillion.
