If you use a smartphone, you probably have come across narrow AI.

It's the level of artificial intelligence we currently have access to, and probably the only one we will have for a few years or decades more.

But don't be deceived by the term narrow. Although this AI has a limited set of abilities and merely tries to mimic the human brain, it's pretty adept when it comes to performing the single task it's designed to do.

It makes self-driving cars a reality, recommends the products you're more likely to buy and movies you'll be interested in watching, and even keeps your email inbox free of spam messages.
