The main user of computers: it might change from humans to AI! Perplexity has launched the Personal Computer; Simply put, Perplexity Personal Computer = "Convenient Deluxe Lobster": it's a convenient version of AIAGENT that can work for you 24/7. This should also be the form that most people will accept in the future: you get a server, log in, and it's ready to use, the kind that anyone can use without pain. Then I see a potential paradigm shift in future interaction patterns: For the past decade or so, the subject of personal computers has always been humans. You open a Mac, click on the browser, switch software, find files, copy and paste, log in to accounts. The computer is your tool. But in the future, could the subject possibly change to "AI": the work on your computer will no longer require you to operate every step manually, but rather hand over the goals to a resident agent, allowing it to run continuously, monitor continuously, and process continuously. Apple's strongest moat over the years is not just hardware or system smoothness, but rather: your digital life naturally revolves around my devices. The official narrative of Apple Intelligence follows this logic: intelligent capabilities are deeply integrated into iPhone, iPad, and Mac, with many requests processed on the device side; more complex requests are handed over to Private Cloud Compute, emphasizing that data is not collected by Apple. So Apple's approach is: to treat AI as a system-level capability, continuing to strengthen device centralization. However, the popularity of various agents like Perplexity and Openclaw provides a new way of thinking: do we really need to first own an operating system or a chip ecosystem, or can we let AI directly occupy the "layer that acts for you" on an existing Mac? In other words, Apple guards the device entry, while agent-type computer services seize the execution entry. Which of these two entries will be more important in the long run? It might not be the former; what if the future personal computer entry is not a screen, but an agent? The truly sticky one may not necessarily be the most elegant, but the one that saves users the most time.
