Google’s genius is twofold. It has a better understanding of computer networks and how to retrieve useful information within them than any of its predecessors. The company has also worked out how to get useful data of its free service from users. If you use Google a lot, everything you search for, whatever you show an online interest in is accumulating in a database somewhere. One day it will contain enough information on you to provide an eerily accurate cyber image of your tastes and preferences. Google’s primary intention is not to snoop on you, though governments like that of the US have already taken note of its potential, not to mention every business interested in online marketing.
