We鈥檝e talked quite a bit about artificial intelligence (AI) around here lately. It can do some pretty great stuff, like manage your emails for you and power your digital butler. Like with anything we use super often though, we wanted to know what it really is. Can a machine or a piece of software really be 鈥渋ntelligent?鈥

Sorry to disappoint, but it鈥檚 not really a yes or no answer, since our definition of artificial intelligence changes so often. For example, what might have been considered AI five years ago may now just be thought of as standard 鈥 nothing special about it. Roll up your sleeves, because we鈥檙e about to get our hands dirty.

What AI Actually Is

AI is intelligence that isn鈥檛 exhibited by humans (this might seem obvious, but hang in there). An 鈥渋deal鈥 intelligent machine analyzes its environment and acts on whatever it thinks will have the greatest chance of success. In layman鈥檚 terms, AI is when a machine or software mimics human brain functions like learning and problem-solving. Things currently categorized as AI include speech recognition, playing games like chess against humans, self-driving cars, etc.

One especially popular trend over the past couple of years has been getting apps to recognize natural language; for example, searching your email with a phrase like 鈥渆mails from Annie last week鈥 as opposed to something like 鈥渇rom:Annie, date:11-25-16.鈥 Nobody鈥檚 got time to memorize formats like that.

Believe it or not, AI isn鈥檛 all computer science and math, because those aren鈥檛 the only things that contribute to natural intelligence, the kind humans have. It also draws on psychology, linguistics and even philosophy. (Basically, computers have to go to college too.)

How You (Yes, You) Use It Every Day

No, AI isn鈥檛 just for the super science-y people, unless you count anyone who鈥檚 ever used Siri, Amazon Echo, Google Assistant or even Facebook as super science-y. Yep, you reap the benefits of AI all the time and probably don鈥檛 even notice it aside from an 鈥渙h that鈥檚 cool, it actually did what I wanted!鈥 Like when you ask Siri to add something to your calendar and you think it might be a little too complicated but, like a champ, she pulls through. Or when something actually interesting and relevant to you pops up on your Facebook Newsfeed. But how do all those apps do it? The term of the day is machine learning. This is the really good stuff.

Machine learning is when a machine, app, etc. learns new things without being explicitly programmed to do so. For humans, this is like somebody telling you that they like Harry Potter, so you guess that they probably also like Game of Thrones, since both are in the fantasy genre.

Relevant stuff coming up on your Newsfeed happens in a similar way; Facebook鈥檚 algorithms work behind the scenes to identify patterns and judge the probability that you鈥檒l like or comment on something that鈥檚 similar to content you鈥檝e interacted with before. That鈥檚 why it鈥檚 so easy to get lost down the Facebook rabbit hole. Humans do this all the time by recommending stuff to each other, so we don鈥檛 think of it as all that fancy, but it really is!

Imagine a (very near) future where you can tell an app five of your best friend鈥檚 interests and it can come up with THE perfect gift every time. A no-stress holiday season? Count us in.
