Today, the events {#blank#}1{#/blank#} in realistic-looking or-sounding video and audio recordings need never have happened. They can instead be {#blank#}2{#/blank#} automatically, by powerful computers and machine-learning software. The catch-all term for these computational productions is "deepfakes".

    The term first appeared on Reddit, a messaging board, as the username for an account which was producing {#blank#}3{#/blank#} videos. An entire community {#blank#}4{#/blank#} up around the creation of these videos, writing software tools that let anyone automatically {#blank#}5{#/blank#} one person's face onto the body of another. Reddit shut the community down, but the technology was out there. Soon it was being applied to political {#blank#}6{#/blank#} and actors.

    Tools for editing media {#blank#}7{#/blank#} have existed for decades—think Photoshop. The power and peril of deepfakes is that they make fakery cheaper than ever before. Before deepfakes, a powerful computer and a good chunk of a university degree were needed to produce a realistic fake video of someone. Now some photos and an Internet connection are all that is required.

    The consequences of cheap, widespread fakery are likely to be {#blank#}8{#/blank#}, albeit slow to unfold. Plenty worry about the possible impact that believable, fake footage of politicians might have on civil society—from a further loss of trust in media to the {#blank#}9{#/blank#} for electoral distortions. These technologies could also be deployed against softer targets: it might be used, for instance, to bully classmates by creating imagery of them in embarrassing situations. In a world that was already saturated with {#blank#}10{#/blank#} imagery, deepfakes make it plausible to push that even further.

    Thank you for choosing me as the best{#blank#}1{#/blank#}. In our school, I'm really happy to share with you how passionate I am about sports and what I do to{#blank#}2{#/blank#}. I'm a big{#blank#}3{#/blank#}of many sports, including basketball, football and gymnastics. I love to watch these events on TV at the weekend. I also{#blank#}4{#/blank#}regularly, too. In the morning. I often {#blank#}5{#/blank#}on the running{#blank#}6{#/blank#}for about half an hour. I don't run too fast or for too long so that I have enough{#blank#}7{#/blank#}for the day. In the afternoon, I usually play football or basketball. I'm on the school football team. The training is always {#blank#}8{#/blank#}, but we all do our best, since we all want to{#blank#}9{#/blank#}on the team when playing against other schools. Believe it or not, we also occasionally do yoga in the{#blank#}10{#/blank#}! It helps relax our muscles and focus our minds. If you want to become fit and healthy, my advice is to try different sports and activities to see which one you enjoy the most.

The programme attracted millions of {#blank#}1{#/blank#}.

People came from all over the world to {#blank#}2{#/blank#}her work.
