Carl Pei, CEO of Nothing, predicts the obsolescence of smartphone apps as AI agents become the primary interface for user-device interaction. Speaking at SXSW, Pei highlighted the stagnation in smartphone usage patterns, which have remained largely unchanged since the iPhone's introduction. He envisions AI-first devices that understand user intent and proactively complete tasks, eliminating the need for multiple app navigation. Pei argues that future interfaces should cater to AI agents rather than human workflows, suggesting a shift towards systems that anticipate user needs and offer unsolicited suggestions. Nothing recently raised $200 million in Series C funding to support its vision for AI-driven devices.
