Carl Pei, co-founder and CEO of Nothing, has stated that smartphone apps will disappear as AI agents take their place in the future. Pei's vision involves a device powered by AI agents, not running apps, and an interface designed for the AI agent to use. This vision helped Nothing secure its $200 million Series C funding round last year. He expanded on his vision for an AI-first device and suggested that it could learn a user's intentions long-term, giving users nudges to achieve goals without needing to be commanded to. The future of smartphones or operating systems should be more user-friendly and less complex.
