Astrophysicist Neil deGrasse Tyson shared a video that left many viewers uneasy about the growing power of artificial intelligence (AI). The clip began with what appeared to be Tyson himself saying the Earth is flat, a shocking statement that immediately grabbed attention. Moments later, the real Tyson appeared, revealing that the earlier part was an AI-generated deepfake meant to show how easily truth can be distorted. The video, titled “It’s Getting Harder to Know What’s Real,” highlights how deepfakes can convincingly imitate real people, even respected figures like Tyson. He used the example to warn people on social media about how this technology can be misused and how difficult it is becoming to tell fact from fiction. Tyson Explains His Concern About Deepfakes After revealing the truth, Tyson explained that while deepfakes can be entertaining when they are clearly parodies, they cross a line when they deceive people. “I didn’t think much about deepfakes until I got deep-faked,” he said. “The early stuff is fine if it’s parody, and if it is obvious it’s parody. But when you do this and the viewer does not know it’s a parody, then you are crossing a line.” Tyson further noted that he’s not the only public figure to experience this, saying that many celebrities have been deepfaked in ways that harm their credibility or twist their actual words. His warning comes as AI tools become more advanced and accessible, making it easier for anyone to manipulate content. Yeah.

A user wrote, “Deepfakes are becoming too good. It’s getting harder to tell.” Another said, “Damn. Honestly convinced the second segment was also a deepfake.” Others expressed worry about the broader implications of such technology. “How will we ever know what’s real anymore?” asked a person. Another suggested blockchain could play a role in verifying authentic content, saying, “This is where blockchain has a place for culture… content chains matter for storing knowledge.” What Is Deepfake Technology? Deepfake technology uses artificial intelligence to create fake videos, images or audio that look and sound real. It can make someone appear to say or do things they never did. Apps using this technology have become extremely popular, with tools like Sora gaining over a million downloads in just a few days on the Apple App Store.
