Many TikTokers use AI to create deepfakes of Taylor Swift and celebrities to share videos about knowledge, but this is also controversial.

According to CBC News , a wave of deepfake videos about celebrities like Taylor Swift, Ice Spice, and Drake are appearing on TikTok. However, the content is not intended to be fraudulent or pornographic, but to explain theories of mathematics, physics and engineering, aimed at children, pupils and students.

For example, in a video on the account @onlocklearning , a deepfake of rapper Ice Spice explains logarithmic functions. The video has more than 10 million views and hundreds of comments. In another video with more than 5 million views, “Taylor Swift” and “Kim Kardashian” talk about integral calculus. Below, the author explains the AI-generated video and the related disclaimer.

“This is not Drake’s real audio or video. All images and words are computer-generated to help people learn about mathematics, physics and engineering,” one account stated.

The comments below the video are mostly supportive. “I grasped that knowledge in a minute, what would have taken my teacher 1-2 class periods,” one user commented.

However, psychologists also expressed concern about using deepfakes about famous people to convey information. The knowledge in the video may be inaccurate, while children are “at risk of completely trusting or developing relationships with the AI characters themselves”.

“Videos can help a person absorb knowledge in a very short time, but the question is how much they actually learn from these videos,” said Professor Krista Muis of McGill University in Montreal, Canada told PetaPixel .

Deepfake is a combination of “deep learning” and “fake”, emerging in 2018 and flourishing today. Being able to create or transplant anyone’s face, voice… makes deepfake a concern in spreading fake and pornographic news. Experts fear that deepfake will become an attack weapon for political purposes in areas with low population levels and not yet fully equipped with digital knowledge. False information can lead to protests, riots, and instability.

“Deepfake offers huge commercial and creative opportunities, but is also a technology that could be weaponized in the future,” Nina Schick, a deepfake expert, told the BBC .
