Carl Pei, co-founder and CEO of Nothing, believes the app era is ending. Speaking at SXSW in Austin on March 18, 2026, Pei outlined a vision where artificial intelligence agents replace the app-centric interfaces that have dominated smartphones for two decades, fundamentally reshaping how users interact with their devices.
Key Takeaways
- Carl Pei predicts apps will disappear as AI agents handle user intentions automatically
- Current smartphone interfaces have remained unchanged for approximately 20 years despite hardware advances
- Nothing raised $200 million in Series C funding last year to develop AI-first smartphones
- Grabbing coffee currently requires four separate apps: messaging, maps, ride-sharing, and calendar
- AI agents will eliminate repetitive app-switching by understanding user context and acting proactively
Why Smartphone Interfaces Have Stalled
Pei argues that the fundamental user experience on smartphones has not evolved meaningfully in two decades. Lock screens, home screens, and app icons remain the dominant paradigm despite revolutionary advances in processing power, connectivity, and artificial intelligence. According to Pei, “The current way we use phones is very old-school… it hasn’t really changed for like, 20 years”. This stagnation persists not because designers lack imagination, but because the app-based model has proven economically resilient and familiar to billions of users. Yet familiarity does not equal efficiency.
The friction of app-switching is precisely what Pei targets. Every task requires context-switching: opening one app, exiting it, opening another, repeating the cycle. This fragmentation forces users to manually orchestrate their intentions across disconnected software silos. Pei sees this as an architectural problem waiting for an AI-driven solution.
How AI Agents Will Replace Apps
Pei’s core premise is straightforward: AI systems that deeply understand user behavior and context can execute intentions without requiring explicit app selection. “I know you very well, and if I know your intention, I just do it for you”. Rather than tapping through maps, messaging, ride-sharing, and calendar apps to arrange coffee with a friend, an AI agent would recognize the intention and coordinate across all necessary services smoothly. Pei describes the current experience bluntly: “Let’s say we want to grab coffee. That’s an intention. But to execute that intention, we have to go through so many different steps and so many different apps. It’s probably like four apps to grab coffee with somebody — some messaging app, some kind of maps, Uber, calendar”.
This vision requires phones to shift from reactive tools (waiting for user input) to proactive agents (anticipating user needs). Nothing’s $200 million Series C funding round, closed in 2025, positions the company to build hardware and software specifically optimized for this AI-first paradigm rather than retrofitting AI onto existing app-centric interfaces.
A Warning to App Developers
Pei’s message carries implicit risk for app-dependent startups and established software companies. He stated directly: “In terms of AI in software, I think people should understand that apps are going to disappear. So, if you’re a founder or a startup and your app is like where the core value lies, that will be disrupted whether you like it or not”. This is not a gentle suggestion — it is a prediction of structural obsolescence.
Current AI tools like ticket booking and reminder-setting represent only the beginning. Pei dismisses these as “super boring in the long run,” implying that truly transformative AI will operate at a level of autonomy and personalization far beyond today’s narrow-task assistants. The implication is clear: apps that survive will be those whose core value exists outside the smartphone interface, or those that successfully integrate into larger AI agent ecosystems.
Is This Vision Realistic?
Pei acknowledges that apps will not vanish overnight. The transition will take years, and legacy systems will persist. The harder question is whether AI can genuinely understand user intention with the accuracy required to act autonomously without constant correction. A booking agent that misunderstands preferences, a messaging agent that sends messages to the wrong contact, or a calendar agent that schedules conflicts would quickly erode user trust. The stakes are higher than app convenience — they involve decision-making authority over user actions.
Nothing’s pitch for AI-first phones with “personalization accurate enough to avoid user double-checks” suggests the company believes it can solve this trust problem. Whether that claim holds up in real-world deployment remains unproven, but the direction is unmistakable.
What Happens to iPhone and Android?
Apple and Google dominate smartphone operating systems, and both have invested heavily in AI features. However, Pei’s critique applies to their current architectures: iOS and Android are fundamentally app-centric platforms with AI layered on top. A truly agent-first OS would require rethinking the entire interface paradigm, not just adding AI features to existing app drawers. Nothing’s position as a smaller, newer manufacturer may allow it to build without legacy constraints, though achieving scale would be another challenge entirely.
FAQ
When will apps actually disappear from smartphones?
Pei does not specify a timeline, but suggests this is a long-term transition, not an immediate shift. Current apps will coexist with AI agents for years as the technology matures and user trust builds. The full transition likely spans a decade or more.
What does Nothing’s AI-first phone look like?
Nothing has not yet revealed a specific product with demonstrated AI agent capabilities. The $200 million Series C funding signals intent to develop such devices, but concrete products and timelines remain undisclosed.
Could AI agents actually understand my intentions accurately?
That is the central technical challenge. Pei claims Nothing aims for personalization “accurate enough to avoid user double-checks,” but achieving this at scale — across diverse users, contexts, and edge cases — remains speculative without shipping products to test against real-world behavior.
Pei’s vision represents a genuine departure from the app-centric paradigm that has defined smartphones since the iPhone. Whether Nothing can deliver on this promise, and whether users will trust AI agents with autonomous decision-making, will determine whether his prediction becomes prophecy or cautionary tale. For now, the app era continues — but Pei’s warning suggests the clock is ticking.
