Advancements in AI and machine learning have significantly improved researchers' understanding of animal communication, particularly among beluga and sperm whales. Behavioral ecologist Jaclyn Aubin utilized machine learning to analyze whale calls effectively, leading to insights about their communication. While some scientists remain optimistic about future breakthroughs, others caution that fundamental barriers may limit understanding. Ultimately, the goal is to grasp what matters in whales' lives to inform human behavior towards their conservation.
