There was a time, not long ago, when consumers cast a wary eye the product quality, uncertain customer service and, most of all, the security of online transactions.

There was a time when online security was, more or less, a duel between smart guys. The bad smart guys were trying to outwit the good smart guys. Artificial intelligence and machine learning give the good guys an electronic army. As technologies advance and become more refined, we will see AI applied to more and more areas that currently require human judgment.
