A blunt prediction about the iPhone’s future
A striking forecast is reigniting debate over how long the smartphone era will last. In a recent remark, Callaghan said, “We’re not going to be using iPhones in 10 years,” adding that he “kind of” doesn’t think people will be using them in five years. The comments, while brief, touch a nerve in the technology industry: whether the next major computing platform will make today’s dominant device feel obsolete.
The statement is notable not because smartphones are suddenly disappearing—global reliance on mobile devices remains entrenched—but because the pace of platform shifts has accelerated. Over the last two decades, consumer tech has moved from desktop-centric computing to laptops, then to app-driven mobile ecosystems led by Apple and its iPhone. The next transition, many companies are betting, will be defined by AI and new form factors that reduce the need to pull out a rectangular screen dozens of times a day.
Why the iPhone is central to the platform debate
The iPhone is more than a product; it is the anchor of Apple’s services and hardware ecosystem and one of the most influential consumer devices ever made. For years, the smartphone has served as the default hub for communication, entertainment, payments, navigation, identity verification, and work. Replacing it would require not only better hardware, but a new interaction model that is easier, faster, and more trusted than tapping a screen.
That is the lens through which industry observers interpret Callaghan’s prediction: not necessarily as a literal end to smartphones, but as a sign that the “primary” device could change. In previous platform shifts, older devices didn’t vanish overnight—they became secondary. Desktops are still widely used, yet many people now reach for their phones first.
What could replace smartphones?
Several technologies are vying to become the next everyday interface. None has yet proven it can fully displace the smartphone, but each is shaping the conversation.
AI-first assistants and ambient computing
The rise of powerful generative AI models has renewed interest in “ambient computing,” where users rely less on apps and more on conversational systems that complete tasks across services. In this vision, a person asks an assistant to handle messaging, bookings, research, and purchasing without navigating multiple screens. If assistants become accurate, secure, and deeply integrated with daily life, the smartphone could become a background device rather than the center of attention.
Wearables and “screenless” devices
Smartwatches, earbuds, and other wearables already offload some smartphone tasks, from notifications to payments and health tracking. The next step would be wearables that can handle more complex interactions—through voice, gesture, or subtle displays—without requiring a phone nearby. For such devices to replace a smartphone, they would need reliable connectivity, strong battery life, robust input methods, and a compelling reason for consumers to switch.
AR glasses and spatial computing
Augmented reality glasses have long been pitched as a successor to the smartphone, promising hands-free access to information layered onto the real world. Recent advances in optics, sensors, and on-device processing have improved the feasibility of this idea, though major hurdles remain. Comfort, cost, privacy concerns, and social acceptance are critical barriers. Still, “spatial computing” is increasingly seen as a potential new platform, especially if it can deliver productivity and communication benefits without isolating users.
Why five years may be too soon
Even in an industry accustomed to rapid change, a five-year timeline is aggressive. Smartphones are supported by mature supply chains, established developer ecosystems, and consumer habits built over more than a decade. The iPhone in particular benefits from deep integration with Apple’s hardware, software, and services—an ecosystem that encourages users to stay.
For a new platform to meaningfully reduce smartphone usage, it must overcome several practical constraints:
- Infrastructure: connectivity, identity, payments, and authentication systems are built around phones.
- Developer support: apps and services must migrate to new interfaces without breaking user experiences.
- Trust and privacy: always-on devices like glasses or assistants raise heightened surveillance and data concerns.
- Cost and durability: smartphones are relatively affordable compared with cutting-edge wearables and AR hardware.
Historically, platform transitions take longer than predictions suggest. New devices often coexist with incumbents for years, gradually absorbing use cases until the older device becomes less essential.
What the prediction signals for the industry
Still, Callaghan’s comment underscores a real shift in how technology leaders think about the next decade: the smartphone is no longer assumed to be the final form of personal computing. Companies are investing heavily in AI-driven interfaces, wearables, and AR experiences precisely because the rewards for owning the next platform are enormous—control over distribution, monetization, and user attention.
For Apple, the question is not simply whether the iPhone will disappear, but how the company evolves if the center of gravity moves away from phones. For competitors and startups, the statement is a reminder that the market remains contestable. If a new device can deliver the same utility with less friction—and do so safely—it could redefine what “personal computing” looks like.
Bottom line
Whether or not the world stops using iPhones in five to ten years, the prediction captures a growing expectation: the next wave of technology may be less about better screens and more about AI-powered, always-available computing that blends into daily life. The smartphone may not vanish—but its dominance is no longer guaranteed.
