  • Which of these three faces do you think is the oldest?

  • A, B or C?

  • The answer is actually none of them, because none of these people were ever born.

  • These faces were all generated by artificial intelligence.

  • Now, thinking about artificial intelligence, look carefully at these two paintings.

  • Which of these does your mind think is created by AI?

  • Is it painting A or painting B?

  • Give up?

  • The clue is in the signature.

  • The AI seems a bit busted on this one.

  • But someone loved it as it went at an auction for $432,500.

  • To explain how these images are generated, let's first look at these images of fruit.

  • By now, you know that one isn't real, but is it the apples or the oranges?

  • If you said apples, you're right!

  • Essentially, a system is fed hundreds of images to learn from.

  • It's then split into two systems.

  • System 1's job is to create a convincing image of an apple,

  • and system 2 is designed to figure out which images of apples are fake.

  • This is known as a generative adversarial network.

  • If system 1 fails at tricking, it continues to evolve its apple designing skills,

  • and if system 2 fails at identifying the fake, it must also improve its ability to catch a fake.

  • This ultimately creates a feedback loop that generates extremely believable images.

  • Now, let's try to relax and listen to some music while you try to deduce which is composed by a computer.

  • Turns out that composition A is generated by a machine learning system called Emily Howell,

  • which was created in the 90s and learned from a library of music to create original pieces.

  • And composition B?

  • That's by Johann Sebastian Bach.

  • A larger library of music will give the machine learning networks more data to learn from, and the same is true for video.

  • Because we upload such huge amounts of video content online,

  • neural networks have begun to create convincing fake videos.

  • Here's a video of the 44th President of the United States, Barack Obama.

  • People not trapped by our past, but able to remake ourselves as we choose.

  • But today, our immigration system is broken, and everybody knows it.

  • And here's another.

  • It's been less than a week since the deadliest mass shooting in American history.

  • And foremost in all of our minds has been the loss and the grief felt by the people of Orlando.

  • Which of these two are real?

  • Video A or B?

  • Known as a deep fake video, video B is generated using AI.

  • With over 14 hours of footage from the president's weekly addresses, neural network AI is able to model the shape of Obama's mouth,

  • and uses audio from one of Obama's previous addresses.

  • But can AI generate convincing synthetic audio?

  • Listen to this phone call.

  • How can I help you?

  • Hello?

  • Hello, what's up, man?

  • Hey, um, I wanted to know what are your hours for today?

  • 10 a.m. to 6:30 p.m.

  • Okay.

  • Got it.

  • Thank you for your time.

  • No problem sir.

  • Bye.

  • Can you tell which of the callers is human?

  • Voice B, the voice you hear asking about the hours the business was open, was fake.

  • We're relying more and more on technology today, which is making our lives easier.

  • Much like SimpliSafe, the sleek new home security system who sponsored today's video.

  • We bought a house recently and finally realized what it feels like to go anywhere and be like, okay legit we're probably gonna be robbed right now, and the stats are in.

  • America has a robbery every 15 seconds, most of which happen while you're at work.

  • So join our new zen life by going to simplisafe dot com slash asap and ease your mind.

  • Importantly for us in our new pad is that it looks cute.

  • The design is awesome, it's intuitive to set up and use, you barely notice the sensors are there,

  • and we like that it does cool things like remind you if you left the door open because Gregg literally does that all the time.

  • He leaves the door wide open when he leaves.

  • In the event of an actual break-in, it can immediately contact the police.

  • We literally just set up our own at home, and it's just one of those things where you get like peace of mind knowing that it's there for you.

  • And it can even tell the difference between a pet and an intruder!

  • So go to simplisafe dot com slash asap to get yours today and make sure you subscribe for more videos every Thursday.
