Human minds are scaffolded by the tools we create, but what happens when we build tools that can use other tools? 

Cognitive scientist Danielle Perszyk sits down with AI researcher Vibhaa Sivaraman to discuss agent tool use and the future of the digital world. They unpack what it really means to build computer-use agents—not just chatbots with function calls—by exploring personalization, multi-agent collaboration, and the idea of agents as the next “cognitive technology.” As agents begin navigating the web on our behalf, they examine how digital environments might evolve and whether agents should think like us, or complement us in entirely new ways.
