MADRID (AP) — Rafael Nadal is warning about fake online videos of him offering financial advice, and the risks of artificial intelligence. The retired tennis great said on Tuesday he has never endorsed any of the online videos or their messages. “In recent days, together with my team, we have detected fake videos circulating on some platforms. These were generated with artificial intelligence, showing a figure that imitates my image and my voice. “Artificial intelligence is a tool with enormous potential, capable of bringing extraordinary progress in education, medicine, sports, and communication.
