While artificial intelligence (AI) is playing a bigger role than ever in Hollywood, award-winning actor Kelsey Grammer is warning it may be "dangerous." The "Karen: A Brother Remembers" author opened up about his growing concern over AI deepfakes and the potential blurred lines between reality and manipulation. "What I'm a little sad about is our prevalence these days to come up with so many, as they try to say deepfakes," he told Fox News Digital. "You know, the ones who say it usually are the ones who are actually doing it. "Karen: A Brother Remembers" author Kelsey Grammer warns about the dangers of AI deepfakes in Hollywood, expressing concerns over the blurred lines between reality and manipulation.

While the "Frasier" star has acknowledged AI to be beneficial in some capacity, including in the medical field, Grammer shared his reservations about how the system can potentially fabricate someone's identity in seconds.

In the wake of the 2010 Deepwater Horizon disaster in the Gulf of Mexico, oceanographer Kaitlin Frasier of the University of California, San Diego, set out to assess the damage that the massive oil spill caused. "We needed to know what happened to marine mammals," she says. Specifically, Frasier was concerned with the spill's impact on dolphin populations. Trying to track the animals from the surface is expensive and time consuming, so Frasier used a different approach: deploying hydrophones to the seabed to passively record every sound in the ocean. By separating out dolphin vocalizations from the general thrum of ocean noise, Frasier hoped to detect trends in the animals' population density.
