Andrej Karpathy believes that achieving Artificial General Intelligence (AGI) will take a decade due to the need to overcome significant challenges, such as developing continual learning and multimodality in AI agents. He thinks that current AI systems, like large language models, are not yet capable of performing tasks that humans take for granted. Karpathy also discusses the history of AI research and how it has shifted from focusing on specific tasks to trying to create more general agents. He emphasizes that building AGI is a complex task that requires significant advancements in various areas.
