AGI vs ASI: The future of AI-supported decision making with Louis Rosenberg
Dec 16, 202400:54:42Tap to summarizeIn this episode of Neural Search Talks, we have invited Louis Rosenberg, CEO of Unanimous.AI, to discuss the future of AI in decision-making, contrasting the development of artificial superintelligence (ASI) with collective human intelligence systems, such as swarm intelligence. In particular, Louis argues that the advancement of AI should focus on amplifying human intelligence rather than replacing it, drawing from the biological inspiration found in nature, where species evolve by connecting individuals into systems that function as a singular intelligent entity, exemplified by schools of fish and swarms of bees. Tune into our conversation to learn more about how AI can assist humans in disseminating knowledge and making better decisions!
